Abstract:
A multi-channel digital router/signal processor, comprising:a plurality of analog bandpass filters, each receiving a radio frequency analog input signal and providing a filtered output signal; a plurality of voltage control pulse generators, each coupled to a respective one to the analog bandpass filters and generating a plurality of voltage output pulse streams; a plurality of pulse splitters receiving the voltage output pulse streams from the voltage control pulse generators and providing a plurality of duplicate signal pulse outputs of each of the voltage output pulse streams; a plurality of pulse gates receiving said plurality of duplicated signal pulse outputs, said pulse gates providing a plurality of gated pulse train output signals; a plurality of pulse combiners receiving a single gated pulse train output signal from a pulse gate and combining said gated pulse train output signals into a single pulse train output; a plurality of multiply-accumulator circuits receiving said single pulse train output from said pulse combiners, said multiply-accumulator circuits multiplying and accumulating the pulse train output to provide a bandpass filter response output; and a digital processing unit receiving a plurality of pulse train outputs from the multiply-accumulator circuits and providing a digital word output.
