(MATLAB) On the companion website, you will find in the directory Chap exercises/chapter3 a

workspace ex3M2.mat. In this workspace, you will find waveforms of the words “we” and “be” (at

10000 samples/s) in the array we be 10k. The waveforms and a spectrogram of the waveforms are

shownin Figure 3.33. To display the spectrogram andwaveform, use the function specgram ex3p19.m

also in Chap exercises/chapter3. To listen to the waveform, use the MATLAB function sound.m.
