Abstract
A digital radio frequency receiver capable of receiving RF signals at a plurality of signal strengths thereby extending the dynamic range of the receiver without introducing a control loop while allowing a stable gain control algorithm to be implemented in software is described. Various embodiments of a digital radio receiver process a range of signals outside normal analog to digital converter capabilities and bypass the delays resulting from gain control loops.
