Phase-modulation
noun, Electronics.
1.
radio transmission in which the carrier wave is modulated by changing its phase to transmit the amplitude and pitch of the signal.
noun
1.
a type of modulation, used in communication systems, in which the phase of a radio carrier wave is varied by an amount proportional to the instantaneous amplitude of the modulating signal
phase modulation
A method of transmitting signals in which the value of the signal is proportional to the phase angle of a carrier wave. It is often combined with amplitude modulation to transmit digital information via modems.
