Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF1.) Periodic signal
- If a signal changes periodically, both in magnitude and direction at regular intervals, then the signal is called as periodic signal.
- A periodic signal can be sinusoidal or pulsating in nature.
2.) Pulsating signal
- If a current varies periodically from zero to maximum, back to zero, and then repeats, the signal is a pulsating signal.
3.) Direct signal
- Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction.
