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).

What is the period of a repetitive signal?

A periodic signal is one that repeats the sequence of values exactly after a fixed length of time, known as the period. In mathematical terms a signal x(t) is periodic if there is a number T such that for all t Equation 10.10 holds.

How do you find the frequency of sound in Matlab?

f0 = pitch( audioIn , fs ) returns estimates of the fundamental frequency over time for the audio input, audioIn , with sample rate fs .
