(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 It was superseded by MFM and RLL.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 ...

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 master timing control circuit for most electronic applications is a precision signal source. For digital applications, it’s an accurate clock. In RF applications, it’s a carrier source for a ...

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 ...

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, ...
