Frequency Modulation, FM Sidebands & Bandwidth
The bandwidth of a frequency modulated, FM signal depends on a variety of factors including the level and frequency of the modulation, and their levels are important for broadcast and radio communication applications. The bandwidth, sideband formation and spectrum of a frequency

Foster Seeley Discriminator: FM detector / demodulator
The Foster Seeley FM discriminator, detector or demodulator enabled audio to be recovered from frequency modulated signals using a relatively simple circuit . The Foster Seeley circuit is probably most commonly called the Foster Seeley discriminator. This is really a hang-over f

FM Slope Detector / Demodulator
One of the easiest methods of demodulating / detecting FM frequency modulation is to use the slope of a tuned circuit: simple but not very effective. FM slope detection is a concept that can used be recover the modulation from an FM signal. It is simple because it can be used w

Frequency Modulation, FM Detection, Demodulation, Discrimination
In order to use the modulation on an FM signal, it is necessary to extract the modulation, i.e. demodulate or detect the signal. FM demodulation is also called FM detection and sometimes the phrase "FM discrimination" is used, although this term tends to be used with o
