How do you calculate signal period?

You can use the formula ω=2πf where ω is the angular frequency (in rads), with the formula T=1f where T is the period of the signal (in seconds, s).

How do you find the period of a signal in 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 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.

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.
