Spectral analysis can help determine if a signal is periodic and measure the different cycles.

How do you find the period of a periodic function in Matlab?

p = seqperiod( x ) returns the integers that correspond to the periods of the sequences in x . The period p is computed as the minimum length of a subsequence x(1:p) of x that repeats itself continuously every p samples.
