Abstract
A digital receiver includes a digital synthesizer that generates a local oscillating (LO) signal at a selected frequency, and a signal mixer that receives an input signal and generates a mixed output signal in response to shifting a phase of the input signal based on the frequency of the LO signal. A multi-mode dynamic channelizer is selectively operable in a first mode and a second mode. The first mode generates a plurality of individual channels having a channel size defined by a bandwidth and a gain, and the second mode generates a parallelization of a selected channel. In response to operating in the second mode, the multi-mode dynamic channelizer adjusts at least one of the bandwidth and the gain of the selected channel based on the mixed output signal to change the channel size of the selected channel.
