frequency shift keying
(foldoc) | Frequency Shift Keying
FSK
(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.

phase-shift keying
(foldoc) | phase-shift keying
(PSK) A digital modulation scheme that
conveys data by changing the phase of a carrier wave. The
data can either determine the absolute phase relative to the
unmodulated carrier or reference signal ("coherent phase-shift
keying", CPSK) or the change in phase ("differential
phase-shift keying", DPSK). The number of different phases
used determines the amount of data that can be transmitted in
each cycle. Each cycle can be considered to constitute one
"symbol", e.g. with two possible phases, each cycle carries
one bit. The more phases that are used, the less tollerant
to noise the transmissions becomes.
Alternatives to PSK are amplitude-shift keying (ASK) and
frequency-shift keying (FSK).
