transmit digital data, i.e. two different
carrierfrequencies are used to represent zero and one.
FSK was originally used to transmit
teleprinter messages by
radio (
RTTY) but can be used for most other types of radio
and land-line digital telegraphy. More than two frequencies
can be used to increase transmission rates.
