b. Perform and plot spectrogram of PCG. Please also briefly discuss what you observe from this time-frequency domain. Are you able to find correspondence between the time-domain PCG and the time-frequency domain of PCG? (Hint: Use built-in ‘spectrogram’ function,

and make sure to input window, overlap, nfft, and fs. Self define the window, overlap, and fft length for short-time Fourier transform; fs is the PCG data acquisition sampling rate. Practice using Help to understand how to use a MATLAB built-in function)
