Can we say if a signal is periodic or non periodic by just looking at its frequency domain plot? how?

The given signal may be periodic if its frequency spectrum having the fundamental time period repeats at regular intervals of time. The given signal is non periodic when the signal's frequency is random and it is not defined as in sine wave or cosine wave.

Answer:

Explanation:

A signal is said to be periodic signal if it has a definite pattern and repeats itself at a regular interval of time. Whereas, the signal which does not at the regular interval of time is known as an aperiodic signal or non-periodic signal.

A signal is a periodic signal if it completes a pattern within a measurable time frame, called a period and repeats that pattern over identical subsequent periods. The completion of a full pattern is called a cycle. A period is defined as the amount of time (expressed in seconds) required to complete one full cycle.

periodic signal are sine wave, cosine wave, square wave etc. Non periodic signals : A CT signal which does not repeat itself after a fixed time period or does not repeat at all is called as a non periodic signal.
