How do you find the 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.
What is a period in MATLAB?
Description: The period character separates the integral and fractional parts of a number, such as 3.1415 . MATLAB operators that contain a period always work element-wise. The period character also enables you to access the fields in a structure, as well as the properties and methods of an object.
