___________________ is a digital modulation scheme where the phase of the  carrier signal is varied with respect to the binary information. (1 word - abbreviation)

Modulation is a process in which characteristics of carrier signal is changed  and multiplexing is a process in which different signals can be shared a common mediaGroup of answer choicesTrueFalse
