Abstract
A frequency translation module for a broadband multi-channel communication system may include an analog signal converter, a digital channel selection device, and a digital-to-analog (D/A) converter. The analog signal converter is configured to receive a plurality of analog signals, to select analog signals residing in a predefined frequency band, and to convert each of the selected analog signals into a digital signal. The digital channel selection device is configured to process digital signals corresponding to the selected analog signals and to generate a composite output of digital signals representative of the selected analog signals. The D/A converter is configured to translate the composite output to an analog signal output decodable by a receiver. Further, the frequency translation module may include a mixer configured to upconvert the analog signal output to a frequency decodable by the receiver.
