Assume that a speech signal has been sampled at 8000 Hz and then analyzed with MATLAB'S specgram function using the following parameters: Hamming window with length L = 100. FIT length of N = 256, and overlap of 80 points. Determine the resolution of the resulting spectrogram image.
(a) Determine the frequency resolution (in Hz)
(b) Determine the time resolution (in sec)
