A filter circuit directed primarily to use in the CATV industry includes at least one frequency dependent component, such as an RF choke, capacitor or inductor, for attenuating signals over at least a portion of the frequency range of signals which pass through the filter. In a typical application, signals are transmitted and received in both forward and return paths at each end of a multi-channel, two-way communication system. Signals in the frequency range of the return path, or of both paths, are attenuated by a desired amount, which is essentially constant over the frequency range of attenuation. In any case, the circuit component providing the attenuation is frequency dependent, thus providing a number of advantages, such as reducing the number of circuit components, reducing filter size and cost, and/or increasing the filter's electric surge and power handling capabilities.
In a two-way communication system having forward and return paths for signals of respective, first and second frequency ranges, means for attenuating signals in at least one of said ranges, said means consisting of at least one frequency dependent component.
