Block schematic for pitch calculation

(i) The speech signals gives as input to system consists of periodic excitation convolved with the impulse response of the vocal tract which is slowly varying function.

(ii) The FFT block takes the DFT of a signal to obtained the spectrum of the signal. When we take the log magnitude …
