Abstract:
A node for receiving analog signals transmitted within a broadband communication system, the node comprising:a summer for summing the analog signals to generate a summed analog signal; an analog-to-digital (A/D) converter coupled to the summer for converting the summed analog signal into a digital electrical signal; a digital signal processor (DSP) coupled to the A/D converter for filtering the digital electrical signal in accordance with a filter algorithm to generate a filtered digital signal, the DSP including a control port for receiving a control signal indicative of the filter algorithm that is to be used, wherein the control signal programs various processing parameters of the DSP, and wherein the filter algorithm specifies center frequency and bandwidth of a filter used by the DSP to process the digital electrical signal; and a transmitter coupled to the DSP for transmitting the filtered digital signal within the broadband communication system.
