XM has applied for a U.S. patent on a new method of FM modulation. Currently most cars do not include any kind of an auxiliary jack, so the method of choice for satellite radio is through FM ...

FREQUENCY-MODULATION, or the technique of varying the frequency of radio waves for signalling purposes, has been known and used for many years ; but it was not until Armstrong in the United States in ...

It has been hypothesized that auditory detection of frequency modulation (FM) for low FM rates depends on the use of both temporal (phase locking) and place cues, depending on the carrier frequency, ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Inovonics has stopped manufacturing its 531N FM Modulation Monitor after 20 years. That’s it and there ain’t no more. “The model 531 has been a popular product since its launch in 2003 with over 5,000 ...
