What is the difference in Fourier block (Simscape/Electrical/Specialized Power System/ Control & Measurements/Measurements) and FFT block (DSP System Toolbox/Transform)? I have digital signal and I further want to use it for relayong purpose. FFT of signal is need to be taken. But, I could not understand what this Fourier block is doing?

Hi Tushar,

The fft block computes the Fast Fourier Transfrom of the input signal. The Fourier block, however, performs Fourier analysis on the input signal. This block calculates the magnitude and phase of a specified harmonic or dc component of the input signal.
