FFT

Understanding Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT). Simulation and Digital Implementation by means of blocks, not C-code

The DFT and FFT are used mainly to obtain the amplitude of a harmonic component from a periodic signal containing several harmonics. For instance, it is desired to know the 180 Hz harmonic amplitude from a signal. Then, the DFT and FFT are the best choices to do that.
