what is the difference betweeen FM and FSK modulation?

Answer Posted / pozhilan.s

frequency modulation (FM) conveys information over a carrier
wave by varying its frequency. In analog applications, the
instantaneous frequency of the carrier is directly
proportional to the instantaneous value of the input signa.

Frequency-shift keying (FSK) is a frequency modulation
scheme in which digital information is transmitted through
discrete frequency changes of a carrier wave. The simplest
FSK is binary FSK (BFSK). BFSK literally implies using a
couple of discrete frequencies to transmit binary (0s and
1s) information. With this scheme, the "1" is called the
mark frequency and the "0" is called the space frequency.
