WebNext Page. Frequency Shift Keying F S K is the digital modulation technique in which the frequency of the carrier signal varies according to the digital signal changes. FSK is a scheme of frequency modulation. The output of a FSK modulated wave is high in frequency for a binary High input and is low in frequency for a binary Low input. WebIn satellite communications PSK is the most commonly used modulation scheme. FSK is occasionally used in applications for which receiver simplicity is a driver. Detection of the signal from an amplitude-modulated carrier ( demodulating the carrier) may be accomplished using a simple envelope detector.
