also known as FM. used in both analogue and digital systems. a carrier is modulated by a program or modulating source/oscillator. the amount of modulation is called the “index’ and determines the ...

/ c ± n.m / for n = 0, 1, 2, 3, .... where n is the sideband pair number In this expression, the + indicates the upper sidebands, and the - indicates lower ones ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

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 ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Edwin Armstrong was the inventor of the frequency modulation (FM) system, the basis for almost all ...
