FSK stands for Frequency Shift Keying which is a simple form of digital modulation for transmitting data. For example, binary FSK is modulating a series of binary ones and zeroes to a set carrier frequency. The amplitude of the data signal remains constant but the frequency and phase shift will vary with the input. That is, for a binary one, the output frequency will be a certain value added to the carrier frequency and for a binary zero, the output frequency will be a certain value subtracted from the carrier and of opposite phase.
