PULSE-FREQUENCY MODULATION (pfm) is a method of pulse modulation in which the
modulating wave is used to frequency modulate a pulse-generating circuit.
PULSE-CODE MODULATION (pcm) refers to a system in which the standard value of a
quantized wave is indicated by a series of coded pulses that give the modulating wave’s value at the
instant of the sample.
