Common means of modulating data in digital communication Key advantage is that I can send mu ltiple signals using Time Division Multiplexing There are several pulse modulation techniques Pulse Amplitude Modulation Pulse Width Modulation Pulse There are different “flavors” of OFDM according what we put in the Prefix:. data.
