A band pass signal has a center frequency of 15 MHz and a bandwidth of 750 kHz (375 kHz each side of the carrier).
(a) Using the band pass sampling theorem determine the minimum sampling frequency at which the band pass signal can be sampled and reconstructed without error.
(b) By drawing the spectrum of the sampled signal and defining all frequencies of interest, show that the signal can be reconstructed without error if the sampling frequency found in (a) is used.
(c) Starting with the sampling frequency found in (a) consider the effect of increasing the sampling frequency. By how much can the sampling frequency be increased without incurring aliasing errors?
