Problem 1.
Record your first name and use Matlab to plot the whole signal. Select one voiced frame and another
unvoiced frame with width around 30 milliseconds. Apply the following on both frames and show your
answers as plots using Matlab (Justify and comment your results):
a) Plot both frames in the time domain.
b) Compute the spectrum magnitude and phase of both frames.
c) Compute and plot the autocorrelation function of both frames.
d) Compute and plot the cepstrum of both frames.
