摘要：A cable television system (100) includes a head end section (105) for generatinga cable signal; a communication medium (110, 117), such as fiber optic cable and coaxialcable, coupled to the head end section (105) for routing the cable signal through thecable television system (100), and cable taps (200) coupled to the communication medium(110, 117) for receiving the cable signal and providing subscriber drops to subscribers ofthe cable television system (100). As the cable signal is routed through the system (100),the signal levels of the signal decrease, and higher frequencies are attenuated morerapidly than are lower frequencies of the signal. Therefore, taps (200) of the cabletelevision system (100) include equalizer circuits (212) for attenuating lower frequenciesof the cable signal to provide relatively flat signal levels at the subscriber drops. Theequalizer circuits (212) also conveniently attenuate reverse signals, as necessary, so thatrelatively equivalent reverse signal levels are seen by the headend section (105).
