How do you find the time period of a signal?

x(t) = x(t + nT). The minimum value of T that satisfies x(t) = x(t + T) is called the fundamental period of the signal and we denote it as T₀. Examples of periodic signals are infinite sine and cosine waves.

How do you find the period of a signal using FFT?

The peak in an FFT magnitude result represents frequency, which is the reciprocal of the period. Multiply the frequency index reciprocal by the FFT window length to get the period result in the same units at the window length.

How do you find the period of a signal in Matlab?

Period = mean(diff(tv(peaks))); That will give you the period in terms of your sampling times.

How do you find the fundamental period of a discrete signal?

Detailed Solution. Concept: A discrete-time signal is periodic if there is a non-zero integer N ∈ discrete-time such that for all n ∈ discrete-time, x(n + N) = x(n). The smallest value of N is known as the fundamental period.
