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, ...

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 ...

Last month we looked at contributions to the art made by amateur operators, in particular advancements in Amplitude Modulation, or AM, and how it came to give radio its voice. This month, we will look ...

The circuit was designed to function on the middle of the FM band, 98 MHz, since the FM frequency ranges from 88 MHz to 108 MHz. Transmitter – an electronic device that can produce or amplify 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 ...

Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

ABERDEEN PROVING GROUND, Md. — In 1938, the director of the Signal Corps Laboratories at Fort Monmouth, New Jersey, Col. Roger B. Colton, transformed the face and future of Army communications. War ...

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 It was superseded by MFM and RLL.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