Pulse time modulation (PTM) includes

Pulse time modulation (PTM) includes

Options:

a) Pulse width modulation
b) Pulse position modulation
c) pulse amplitude modulation
d) both a) and b)

Correct Answer: 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. The carrier is a train of pulses rather than a continuous signal. In PTM, the timing of the pulses of the carrier is varied in accordance with modulating signal. PTM includes:

- Pulse width modulation
- Pulse position modulation
