What does non periodic signal mean?
On the other hand, a non-periodic signal is any signal that does not repeat itself after any period of time, however large that period may be. Most of the signals we come across in real life are non-periodic. For example, speech is a non-periodic signal.

Signal Analysis in the Frequency Domain
The technique for determining the sinusoidal series representation of a periodic signal is known as Fourier series analysis.
Is Fourier transform for non periodic signals?
Fourier series is defined for periodic signals and the Fourier transform can be applied to aperiodic (occurring without periodicity) signals.
What is periodic signal and frequency domain?
The frequency domain representation of a periodic signal is a line spectrum. It can only have non-zero values at DC, the fundamental frequency, and harmonics of the fundamental. Because periodic signals have no beginning or end, non-zero periodic signals have infinite energy but generally have finite power.
