摘要
A cable television system (400) includes a transmitter (200) for generating a digital optical signal and a receiver (201) for receiving such digital optical signal and converting it to an analog signal. The receiver (201) includes a digital filter (300) disposed between a deserializer (225) and a digital-to-analog converter (230), which digital filter conditions the digital electrical signal received from the deserializer (225). 1o The digital filter (300) is employed as a digital noise mitigation block so as to improve the quality of the signals in the reverse path, returning to the cable television system (400) headend (105).
