than using direct convolution such as MATLAB's conv command. • Using the DFT via the FFT lets us do a FT (of a finite length signal) to examine signal
The first step of the recognition process is the frequency analysis. For computing the DFT spectrum of the input signal we use the fast Fourier transform (FFT).
