[PDF] The Fundamentals of FFT-Based Signal Analysis and Measurement PDF FFT_tutorial

The Fast Fourier Transform (FFT) and the power spectrum are powerful tools for analyzing compute the amplitude and phase versus frequency from the FFT

In general, Fourier transforms are complex functions and we need to plot the amplitude and phase spectrum separately This can be done using the following
