Pulse Amplitude Modulation
Today communication is the heart of the technology. Communication is achieved over a transmitter and a receiver through signals. These signals carry the information through modulation. Pulse Amplitude Modulation is one of the kinds of modulation techniques used in signal transmission. Pulse amplitude modulation is the simplest form of modulation. It is Analog to digital conversion method where the message information is encoded in the amplitude of the series of signal pulses.
