FSK system involves ________ Correct Answer frequency modulation

FSK (Frequency Shift Keying) is a method to transmit digital signals, which are in form of binary data. FSK i.e. Frequency Shift Keying involves frequency modulation that assigns bit values to discrete frequency while ASK assigns bit values to discrete amplitude.
