What Is Pulse Amplitude Modulation?

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

What does pulse amplitude mean?

In telecommunication, pulse amplitude is the magnitude of a pulse parameter, such as the voltage level, current level, field intensity, or power level. ... Pulse amplitude also applies to the amplitude of frequency- and phase-modulated waveform envelopes.

What is purpose of pulse amplitude modulation?

Why is pulse amplitude modulation used? PAM is used to modulate the signal wave during the transmission of data. PAM is a type of analog to digital conversion technique.
