FSK Last modified: Thursday, March 21, 2002

Short for frequency-shift keying, a modulation technique used by modems in which two different frequencies in the carrier signal are used to represent the binary states of 0 and 1. Using FSK, a modem converts the binary data from a computer into a binary form in which logic 1 is represented by an analog waveform at a specific frequency and logic 0 is represented by a wave at a different specific frequency. Compare with PSK.
