WebJul 19, 2015 · The FFT is the Fast Fourier Transform. It is a special case of a Discrete Fourier Transform (DFT), where the spectrum is sampled at a number of points equal to a power of 2. This allows the matrix algebra to be sped up. The FFT samples the signal energy at discrete frequencies. The Power Spectral Density (PSD) comes into play when dealing … WebCross spectral density is a method for comparing the power spectra for two signals. Cross spectral density is also related to other signal comparison metrics, and signal processing engineers should understand which metrics are best to use in different situations.
