Consider the sampling of real signals
a.) Typically, a speech signal that can be understood over a telephone shows frequencies from about 100 Hz to about 5 KHz. What would the sampling frequency fs (samples/ sec) that would be used to sample a speech without aliasing? How many samples would you need to save when storing an hour of speech? If each sample is represented by 8 bits, how many bits would you have to save for the hour of speech?

b.) A music signal typically displays frequencies from 0 up to 22 KHz. What would be the sampling frequency fs that would be used in a CD player?

c.) If you have a signal that combines voice and musical instruments, what sampling frequency would you use to sample this signal? How would the signal sound if played at a frequency lower than the Nyquist sampling frequency?
