8-3) Bandpass sampling
A bandpass signal is confined to the frequency range from 7.5 to 10.5 kHz. Find the allowed ranges of
the sampling rate for this signal. Sketch the amplitude spectrum of a hypothetical message, the amplitude
spectrum of the sampled signal, and the transfer function of a suitable recovery filter if the sampling rate
is chosen in the center of the lowest range available.
