The device includes a first signal path branched from the input node that includes a low-pass filter adapted to conduct the CATV signals and reject the in-home entertainment signals. A second signal path in parallel electrical communication with the first signal path includes a high-pass filter in series electrical connection with a signal conditioning circuit. The high-pass filter is adapted to conduct the in-home entertainment signals and reject the CATV signals. The signal conditioning circuit attenuates and equalizes the in-home entertainment signals when coupled to the coaxial device.

摘要： A dual bandstop filter affects frequencies in a lower passband, first and second stopbands separated by a middle passband, and an upper passband. The filter includes two legs. In one version, one leg is a highpass filter while the other leg is a bandstop filter outputting into a lowpass filter. In a second version, one leg is a lowpass filter while the other leg is highpass filter outputting into a bandstop filter. The first version is preferred when the upper value of the lower passband is around 100 MHz or less, while the second version is preferred when the upper value of the lower passband is around 100 MHz or more. In a third version, one leg is a highpass filter while the other leg is a bandstop filter sandwiched between two lowpass filters, preventing second resonances from the lowpass filter from interfering with desired frequencies in the upper passband.

摘要： A frequency band selection device that can be inserted into a signal transmission line of a CATV system on the premise of a user includes at least two signal path sets between a tap side and a premise side. Each signal path set includes two discrete signal paths, a high frequency signal path for a downstream bandwidth and a low frequency signal path for an upstream bandwidth. The high frequency signal path and the low frequency signal path are separated by a cut-off transition frequency that is different for each signal path set. The device further includes a switch controller having at least two discrete switch positions. The switch controller chooses one of the switch positions as a result of an information signal. Each of the switch positions corresponds to a respective one of the signal path sets.
