FM has better noise (RFI) rejection than AM, as shown in this dramatic New York publicity demonstration by General Electric in 1940. The radio has both AM and FM receivers. With a million-volt arc as a source of interference behind it, the AM receiver produced only a roar of static, while the FM receiver clearly reproduced a music program from Armstrong's experimental FM transmitter W2XMN in New Jersey. In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. In analog frequency modulation, such as FM radio broadcasting of an audio signal representing voice or music, the instantaneous frequency deviation, the difference between the frequency of the carrier and its center frequency, is proportional to the modulating signal. Digital data can be encoded and transmitted via FM by shifting the carrier's frequency among a predefined set of frequencies representing digits – for example one frequency can represent a binary 1 and a second can represent binary 0. This modulation technique is known as frequency-shift keying (FSK). FSK is widely used in modems and fax modems, and can also be used to send Morse code.[1] Radioteletype also uses FSK.[2] Frequency modulation is widely used for FM radio broadcasting. It is also used in telemetry, radar, seismic prospecting, and monitoring newborns for seizures via EEG,[3] two-way radio systems, music synthesis, magnetic tape-recording systems and some video-transmission systems. In radio transmission, an advantage of frequency modulation is that it has a larger signal-to-noise ratio and therefore rejects radio frequency interference better than an equal power amplitude modulation (AM) signal. For this reason, most music is broadcast over FM radio. Frequency modulation and phase modulation are the two complementary principal methods of angle modulation; phase modulation is often used as an intermediate step to achieve frequency modulation. These methods contrast with amplitude modulation, in which the amplitude of the carrier wave varies, while the frequency and phase remain constant.

Basic Principles of Frequency Modulation (1944) US Army Training Film; Kent Smith

Excellent Army training film in which actor Kent Smith (Cat People...) explains the fundamentals of FM radio. US Army Training Film TF11-2069 https://en.wikipedia.org/wiki/Frequency_modulation In telecommunications and signal processing, frequency modulation (FM) conveys information over a carrier wave by varying its instantaneous frequency. This contrasts with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant. In analog applications, the difference between the instantaneous and the base frequency of the carrier is directly proportional to the instantaneous value of the input-signal amplitude. Digital data can be sent by shifting the carrier's frequency among a range of settings, a technique known as frequency-shift keying. FSK (digital FM) is widely used in data and fax modems. Morse code transmission has been sent this way, and FASK was used in early telephone-line modems. Radioteletype also uses FSK. FM modulation is also used in telemetry, radar, seismic prospecting and newborn EEG seizure monitoring. Frequency modulation is known as phase modulation when the carrier phase modulation is the time integral of the FM signal. FM is widely used for broadcasting music and speech, two-way radio systems, magnetic tape-recording systems and some video-transmission systems. In radio systems, frequency modulation with sufficient bandwidth provides an advantage in cancelling naturally-occurring noise. Radio Edwin Howard Armstrong (1890--1954) was an American electrical engineer who invented wideband frequency modulation (FM) radio. He patented the regenerative circuit in 1914, the superheterodyne receiver in 1918 and the super-regenerative circuit in 1922. Armstrong presented his paper, "A Method of Reducing Disturbances in Radio Signaling by a System of Frequency Modulation", (which first described FM radio) before the New York section of the Institute of Radio Engineers on November 6, 1935. The paper was published in 1936. As the name implies, wideband FM (WFM) requires a wider signal bandwidth than amplitude modulation by an equivalent modulating signal; this also makes the signal more robust against noise and interference. Frequency modulation is also more robust against signal-amplitude-fading phenomena. As a result, FM was chosen as the modulation standard for high frequency, high fidelity radio transmission, hence the term "FM radio" (although for many years the BBC called it "VHF radio" because commercial FM broadcasting uses part of the VHF band—the FM broadcast band). FM receivers employ a special detector for FM signals and exhibit a phenomenon known as the capture effect, in which the tuner "captures" the stronger of two stations on the same frequency while rejecting the other (compare this with a similar situation on an AM receiver, where both stations can be heard simultaneously)... An FM signal can also be used to carry a stereo signal; this is done with multiplexing and demultiplexing before and after the FM process. The FM modulation and demodulation process is identical in stereo and monaural processes. A high-efficiency radio-frequency switching amplifier can be used to transmit FM signals (and other constant-amplitude signals)... Normal (analog) TV sound is also broadcast using FM... http://en.wikipedia.org/wiki/Kent_Smith Kent Smith (March 19, 1907 -- April 23, 1985) was an American actor who had a lengthy career in film, theater, and television... His biggest successes occurred during the 1940s in films such as Cat People (1942), Hitler's Children (1943), This Land Is Mine (1943), Three Russian Girls (1943), Youth Runs Wild (1944), The Curse of the Cat People (1944), The Spiral Staircase (1946), Nora Prentiss (1947), Magic Town (1947), The Fountainhead (1949), My Foolish Heart (1949), and The Damned Don't Cry!

However, frequency drift or a lack of selectivity may cause one station to be overtaken by another on an adjacent channel. Frequency drift was a problem in early (or inexpensive) receivers; inadequate selectivity may affect any tuner. An FM signal can also be used to carry a stereo signal; this is done with multiplexing and demultiplexing before and after the FM process. The FM modulation and demodulation process is identical in stereo and monaural processes. A high-efficiency radio-frequency switching amplifier can be used to transmit FM signals (and other constant-amplitude signals). For a given signal strength (measured at the receiver antenna), switching amplifiers use less battery power and typically cost less than a linear amplifier. This gives FM another advantage over other modulation methods requiring linear amplifiers, such as AM and QAM. FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech. Normal (analog) TV sound is also broadcast using FM. Narrowband FM is used for voice communications in commercial and amateur radio settings. In broadcast services, where audio fidelity is important, wideband FM is generally used..

How Oscillator Works ? The Working Principle of the Oscillator Explained
 
09:18
In this video, the working principle of the Electronic Oscillator has been explained. By watching this video, you will learn the following topics: 0:42 What is Oscillator 1:04 How OScillator Works? 4:03 Barkhausen Criteria for Oscillations and mathematical derivation 8:12 Different Types of Oscillators What is Oscillator: The Oscillator is an electronic circuit, which accepts the DC voltage and generates the periodic time varying waveform of the desired frequency. How Oscillator Works: The Oscillator is an amplifier with positive feedback. When the Oscillator is turned ON, then the thermal noise is amplified by the amplifier of the oscillator. The feedback circuit in the oscillator is the frequency selective circuit. It amplifies only one particular frequency from all other frequencies. And over the period of time, the one frequency will get build up and gives the periodic oscillations at the output. Barkhausen Criteria: For sustained Oscillation, 1) the magnitude of the loop gain AB should be equal to 1 (AB =1) 2) Phase Shift introduced by the amplifier and the feedback circuit should be zero. Types of OScillator: Depending on the type of feedback circuit the oscillators can be broadly classified as 1) RC OScillator 2) LC OScillator 3) Crystal OScillator Depending on the arrangement of these R, L, C components, it can be further classified. (Colpitts Oscillator, Hartley Oscillator etc.) Depending on the type of output, the oscillators can be classified as 1) Harmonic Oscillators (Gives Sinusoidal Output) 2) Relaxation OScillators (Gives Non-Sinusoidal Output, Like square wave and Triangular Wave) This video will be helpful to all the students of science and engineering in understanding the working principle of the oscillator. #Oscillator #HowOscillatorWorks Follow me on YouTube: https://www.youtube.com/allaboutelectronics Follow me on Facebook: https://www.facebook.com/ALLABOUTELECRONICS/ Follow me on Instagram: https://www.instagram.com/all_about.electronics/ Music Credit: http://www.bensound.com/

Output Transformers: A Discussion of Basic Principles
 
25:36
In this video I attempt the unenviable task of trying to explain the design and function of one the most significant, yet misunderstood, components in tube amplifiers: the Output Transformer. Topics include: Purpose of the OPT, Winding Ratios, Demonstration of a Method to Measure the Winding Ratio, Consequences of Using Incorrect-Impedance Speakers, Impedance vs Resistance, Impedance Reflection, and how to select the proper OPT for your amp. Be warned: some math is inevitable, but I try to provide sufficient explanation to (hopefully) make it all palatable. Think of this as a video buffet.....consume it all, or simply pick and choose that which appeals to you :) If you enjoy videos featuring classic vintage amps, jukeboxes, homemade electromechanical devices, and clear, basic technical presentations, then please subscribe to my channel.

Oprah Winfrey Interviews Abraham & Esther Hicks: THE LAW of ATTRACTION and THE SECRET (Soul Series)
 
01:18:02
FREE Wealth Training with John Crestani: ► Click HERE: https://manifestmyowndestiny.com/super-affiliate-system-free-training/ Oprah Winfrey Interviews Abraham & Esther Hicks: THE LAW of ATTRACTION and THE SECRET (Soul Series) On Oprah’s XM Radio Show she interviews Esther Hicks about her involvement in "The Secret". Oprah and Esther Hicks also talk about the Law of Attraction, and how Esther Hicks learned to channel Source Energy, called Abraham. ► LAW OF ATTRACTION Booster MP3: https://manifestmyowndestiny.com/loa-booster/ ► Free WEALTH Booster MP3: https://manifestmyowndestiny.com/wealth-booster/ In this video, Oprah talks about why both she and the mainstream population were not yet ready for “Abraham” and Esther. Abraham is the name for the collective entity that channels through Esther Hicks. Oprah is a big fan of spirituality and enjoys talking about anything that has to do with personal development. While she embraces Abraham, she just felt that the general public would not embrace the thing with channeling. For many it seems to be quite “spaced out”. That is why Esther wasn’t invited to one of Oprah’s TV shows. A radio interview is what Oprah thought would be best, and it would be easier to embrace since many her radio listeners are open to things in terms of spirituality. Oprah further talks about the enormous impact that the “The Secret“ movie have done on people, and how the interest is growing for this topic about the Law of Attraction. Esther Hicks who is the co-author of “The Law of Attraction: The Basics of the Teachings of Abraham”, mentions that as inspirational speaker she is not working by herself. She channels a “collective voice” which is called “Abraham”. That is why she likes to call the material that is coming through for “Abraham-Hicks”. During the radio session, there is an opportunity when Oprah gets the chance to communicate with “Abraham”. Esther prepares herself by breathing, relaxing before allowing the collective voice to come through her. Oprah does not really know what to expect when she experiences Esther channeling the collective consciousness, but she is very excited about it. Once Esther is channeling, Oprah notices that Esther is speaking in a little bit different way with another tone to her voice. Esther mentions for Oprah of what Abraham can bring to people. Abraham is not interested in telling people exactly what they should or should not do, because everyone is to create their own true reality. Abraham is only interested in communicating how everyone can create their own life path. Every circumstance and event that you are involved in is attracted to you, by you. With your thoughts, you are able to change any circumstance you want. Oprah concludes that with an understanding of the Law of Attraction, together with the understanding that you deliberately can create your own life, will without doubt show you a way to complete freedom as long as you practice and allow it.

They're just doing the best they can! When "ready", pm me on Facebook including phone number. Contact information below, don't be in a hurry! "Radios not only transform signals into waves, they transform waves into sound" Meter swinging over-modulated radios with a noisy receiver and miscalibrated "S" Meter have been "peaked & tuned", comp-tuned or so-called Hi-Fi mods performed and misaligned by a Golden Screwdriver magician. Yes, magician not technician. Internet, Facebook, and truck stop competition tunes are useless in the Real World. Not only do they produce a noisy receiver, they'll bleed your wallet and all over neighbors too! Years ago, while still accepting walk-ins, this was about 90% of all radio related issues and complaints from customers nationwide .. Still Is!! ****How to recognize**** They'll ask you to "look at the meter" or other test equipment stacked up the wall claiming that a pure waveform on a "O"scope isn't necessary. Odds are it's because they cant! If they did, they'd expose themselves as a Hack. RUN!!! They'll poise their meter farm at you while making strange vocal sounds, whistling or injecting some unknown tone into the mic socket while trying to convince you that distortion is considered rms, average or Bird watts and usable power. NOT! Get That Part? PAY ATTENTION!! Most don't have a clue what each unit of measurement represents, how to derive it or have an accurate way of testing but they sure do put on a show! This might look impressive to some but in reality, these tunes produce "Far Less Usable Power". Sound familiar? Many have fallen for these "tricks" so don't feel bad. "Software Jockeys" claiming to be an "Engineer" (lol) don't do or show you anything useful at all. They either copy and paste (Plagiarism) or talk a lot trying to baffle you with their "BS" while hiding behind a pseudonym (Extra channels, Channel King Boards, CB Kidd, Stinger Boards etc). This type has no integrity, practical or "Real World Experience" at all whatsoever! Ever hear them on the radio? Right! ***Real World Performance*** Do your due diligence! Demand the testing and tuning of your equipment on a minimum 100 MHz **Analog** Oscilloscope, Bird 4314c meter or equivalent and a 1 GHz spectrum analyzer / Service Monitor with a NIST (https://www.nist.gov/) Traceable "Certification of Calibration". It's the only accurate way of measuring spurious emissions, harmonics and true power @ the fundamental frequency replicating "Real World Performance". All test equipment and gear under test including meter, scope, spectrum analyzer, sampler, radio and amp if applicable must be in plain sight at all times while gear is under test, fully modulated. Inducing distortion though meter using un-calibrated test equipment is misrepresentation and an illusion playing on your ignorance while insulting your intelligence! If they cant display everything all at the same time while under test, explain ac volts, pep, pk, cw, rms (Ohms Law), capacitance, inductance and the basic principles of a phase shift then how do you expect them to accurately test, tune or align your system? Ever wonder why they attempt to replicate or imitate everything I do and say but yet fail miserably in a deceiving way?
