What is the difference between periodic and aperiodic signals?

Answer 1

A signal which repeats itself after a specific interval of time is called periodic signal. A signal which does not repeat itself after a specific interval of time is called aperiodic signal.
A signals that repeats its pattern over a period is called periodic signal,

A signal that does not repeats its pattern over a period is called aperiodic signal or non periodic.

Both the Analog and Digital can be periodic or aperiodic. but in data communication periodic analog sigals and aperiodic digital signals are used.

Answer 2

•Non-periodic signal

•pattern not repeated over time

• Both analog and digital signals can b

e periodic or non-periodic

--(a) shows periodic continuous signal (sine wave)

--(b) shows periodic discrete signal (square wave)

•In data comm., we commonly use periodic analog signals and non-periodic digital signals

Answer 3

which repeat periodically. after time T its charactristics are repeated is called periodic signal.
