Abstract
A radio frequency to digital receiver has a modulator sampling a signal at a first rate. The receiver has at least one processing unit. The processing unit has a plurality of digital bandpass filters separating the signal and recombining the signal at a rate less than the first rate. The processing unit has a digital down converter adjusting frequency offset or centering the signal at the rate less than the first rate. The receiver has at least one rate control buffer coupled to adjacent processing units when two or more processing units are within the receiver.
