Description

This report describes how one can use the GC2011 Digital Filter the GC3011 Digital Resampler and the GC3021 Carrier Removal chips to build high performance digital demodulators for most BPSK QPSK and QAM radio signals. In order to simplify the RF front-end these demodulators are fully digital operating off of a single Analog to Digital Converter (ADC) and a single fixed frequency crystal osci
