Question of PCM and ASK

[curious_mind]

I have some confusion regarding Pulse code modulation and amplitude shift keying. Are they not both modulation techniques? Literature provides, PCM as encoding method and ASK as modulation method. Could anybody clarify?

What is the difference between pulse-amplitude modulation (PAM) and pulse code modulation (PCM)?

Answer (1 of 7): Pulse-amplitude modulation (PAM), is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulse. It is an analog pulse modulation scheme in which the amplitudes of a train of carrier pulses are varied according to the sample ...
