Universal Multiple-Band Digital Transmitter Module for CATV Upstream and Downstream

A method, comprising configuring a digital transmitter including

• coupling a reversibly removable module to a generic adaptable reconfigurable digital transmitter module, wherein the reversibly removable module includes an RF filter with a cutoff frequency and a memory that stores parameters that define, at least in part, a specific adapted configuration;
• reading a signal bandwidth from the memory of the reversibly removable module;
• and
• selecting an analog to digital sampling rate of the generic adaptable reconfigurable digital transmitter module as a function of the signal bandwidth.

A method, comprising configuring a digital receiver including

• reading a signal bandwidth from the memory of the reversibly removable module;
• and
• selecting a digital to analog sampling rate of the generic adaptable reconfigurable digital receiver module as a function of the signal bandwidth.

A method, comprising configuring a generic adaptable reconfigurable digital transmitter having a programmable signal conditioner including

• specifying a number of input RF channels;
• specifying an RF bandwidth of an input channel;
• and
• selecting an analog to digital sampling rate of an analog to digital convertor of the programmable signal conditioner as a function of the RF bandwidth of the input channel using a processor/mux of the generic adaptable reconfigurable digital transmitter.

A method, comprising configuring a generic adaptable reconfigurable digital receiver having a programmable signal conditioner including

• specifying a number of output RF channels;
• specifying an RF bandwidth of an output channel;
• and
• selecting a digital to analog sampling rate of a digital to analog convertor of the programmable signal conditioner as a function of the RF bandwidth of the output channel using a processor/demux of the generic adaptable reconfigurable digital receiver.
