Digital implementation of multi-channel demodulators

摘要

A method and circuitry for implementing digital multi-channel demodulation circuits. More particularly, embodiments of the present invention provide a digital multi-channel demodulator circuit. The demodulator includes a frequency-block down-converter that receives a multi-channel analog RF signal and shifts the multi-channel analog RF signal to a lower frequency band. An ADC receives the multi-channel analog RF signal from the frequency-block down-converter and converts the multi-channel analog RF signal to a multi-channel digital RF signal. A digital channel demultiplexer receives the multi-channel digital RF signal from the ADC and demultiplexes the multi-channel digital RF signal into separate digital RF channels.
