What is FSK?

Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier wave. The technology represents digital data by varying the frequency of a carrier signal. A binary '1' (mark) is represented by one frequency, and a binary '0' (space) is represented by another. FSK is commonly used in applications such as modems, radio telemetry, and amateur radio.
