DIGITAL SIGNAL PROCESSING OPTICAL TRANSMITTER

摘要

A node (200) for receiving analog signals transmitted within a broadband communication system (100) includes a summer (205) for summing the analog signals to generate a summed analog signal and an analog-to-digital (A/D) converter (210) coupled to the summer (205) for converting the summed analog signal into a digital electrical signal. The node (200) also includes a signal processor (DSP)(220) coupled to the A/D converter (210) for filtering the digital electrical signal in accordance with a filter algorithm to generate a filtered digital signal. The DSP (220) including a control port for receiving a control signal (215) indicative of the filter algorithm that is to be used. The filtered signal is then transmitted upstream within the system (100) by a transmitter (240) coupled to the DSP (220).
