(1) An earlier magnetic disk encoding method that places clock bits onto the medium along with the data bits. It was superseded by MFM and RLL. FM radio was invented in the early 1930s by Edwin Howard ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

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 ...

In quantum devices, frequency modulation is utilized in controlling interactions. A new article discusses the physics of frequency modulation in superconducting quantum circuits, ultracold atoms, ...

The FM modulator circuit (frequency modulation) is built with a Motorola MC1648P oscillator. Two varactors, Motorola MV-209 are used to frequency modulate the oscillator. The 5000 Ω potentiometer is ...

You're going on a road trip. This isn't a question - it's summer and I know you're gearing up to take the family on that Griswold vacation that will leave you craving anything but fast food and ...

The author is president of Omnia Audio in Cleveland. The FM stereo transmission system employed in worldwide broadcasting has been in place since 1961. The rules governing stereophonic performance ...
