What are the types of pulse modulation?
Pulse modulation is further divided into analog and digital modulation. The analog modulation techniques are mainly classified into Pulse Amplitude Modulation, Pulse Duration Modulation/Pulse Width Modulation, and Pulse Position Modulation.
What uses pulse modulation?
Pulse modulation methods are used to transfer a narrowband analog signal, such as a phone call, over a pulse stream. Some schemes use a digital signal for transmission, making them essentially an analog-to-digital conversion.
What are the examples of modulation?
For example, the modulation signal might be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal representing a sequence of binary digits, a bitstream from a computer.
