Types of analog pulse modulation systems

Types of analog pulse modulation systems are

Options:

a) Pulse amplitude modulation
b) Pulse time modulation
c) Frequency modulation
d) Both a) and b)

Correct Answer: d) Both a) and b)

Explanation:

In pulse modulation systems, the carrier is a train of pulses rather than a continuous signal. The parameters of the pulses are varied according to the instantaneous value of the modulating signal. There are two types of pulse modulation systems:

- Pulse amplitude modulation
- Pulse time modulation
