PULSE MODULATION

In pulse modulation train of pulses is used as the carrier wave. Here we will discuss in details, Pulse modulation and pulse modulation techniques like Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM)/Pulse Duration Modulation (PDM), Pulse Position Modulation (PPM) and Pulse Code Modulation (PCM). Here Basics and waveform of each Pulse Modulation Technique has been discussed in detail.
