Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

The transmission of a fixed frequency that has been altered (modulated) to "carry" data ... The receiving device detects the steady 2.5 GHz carrier and demodulates it to obtain the data within.

Especially in the frequency bands below 1 GHz, you might find yourself interfacing with a module at really low level, where you might be tuning modulation parameters. The following overview should ...

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 It was superseded by MFM and RLL.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