Frequency-shift keying
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal., p 509 The technology is used for communication systems such as telemetry, weather balloon radiosondes, caller ID, garage door openers, and low frequency radio transmission in the VLF and ELF bands.
Frequency Shift Keying
<communications> (FSK) The use of frequency modulation to
transmit digital data, i.e. two different carrier
frequencies 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.

Multiple frequency-shift keying
MFSK; Multi-frequency shift keying; Mfsk16; MFSK8; MFSK16; Mfsk4; Mfsk32; Mfsk64
Multiple frequency-shift keying (MFSK) is a variation of frequency-shift keying (FSK) that uses more than two frequencies. MFSK is a form of M-ary orthogonal modulation, where each symbol consists of one element from an alphabet of orthogonal waveforms.

Frequency-shift keying
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is encoded on a carrier signal by periodically shifting the frequency of the carrier between several discrete frequencies. The technology is used for communication systems such as telemetry, weather balloon radiosondes, caller ID, garage door openers, and low frequency radio transmission in the VLF and ELF bands. The simplest FSK is binary FSK (BFSK), in which the carrier is shifted between two discrete frequencies to transmit binary (0s and 1s) information.
