[PDF] The Fundamentals of FFT-Based Signal Analysis and Measurement
The basic functions for FFT-based signal analysis are the FFT, the Power Spectrum, and the Cross Power Spectrum Using these functions as building blocks, you can create additional measurement functions such as frequency response, impulse response, coherence, amplitude spectrum, and phase spectrum
