Abstract
A satellite receiver is provided which downconverts an incoming band of signals received at a carrier frequency to a signal spectrum centered about an intermediate frequency (IF). The IF signal spectrum is filtered to provide a group of signals therefrom. The group comprises a subset of all the signals in the incoming band of signals. The group of signals from the IF signal spectrum is sampled at a high frequency which is greater than the highest frequency present in the group but lower than the intermediate frequency, in order to provide the group of signals at baseband directly from the IF signal spectrum.
