The present disclosure is directed to an apparatus () and method () for controlling a filter circuit () in a signal communication device (). The apparatus () and method () of the present disclosure receives () an indication of a plurality of channels used to transmit upstream communication signals in an upstream communication portion of a frequency range. Furthermore, the apparatus () and method () of the present disclosure determines () a maximum frequency value among all frequencies used by the plurality of channels based on the indication and adjusts () a filter response in a filter circuit () used to separate the upstream communication signals from the downstream communication signals in a communication device () based on the determined uppermost frequency value.

Method and apparatus for controlling a filter circuit in a signal communication device

An apparatus and method for applying signals into a filter circuit is disclosed. The apparatus includes a filter circuit that filters an input signal and outputs a signal in a first frequency range, and a filter circuit that filters the input signal and outputs a signal in a second frequency range that is different from the first frequency range, wherein the second filter circuit includes an interface circuit for inserting a signal used to receive the first frequency range signal. The method includes receiving a signal containing content from a first source in a first frequency range and content from a second source in a second frequency range, providing filtering to produce a signal containing the first content, providing filtering to produce a signal containing the second content, and applying a signal to second content signal processing circuitry, the signal provided used for receiving the content from the first source.

Apparatus and method for inserting electrical power or control signals into a diplexer circuit

An apparatus and method for filtering a signal is described. The apparatus includes a first singly terminated filter that filters a signal in a first frequency range, and a second singly terminated filter that filters the signal in a second frequency range, the inputs of the filters being connected together, wherein an element of the first filter is coupled to an additional element to form a frequency response transmission zero in a stopband frequency range of the first filter. The method includes receiving a signal, the signal containing content from a first source in a first frequency range and content from a second source in a second frequency range different than the first range, applying filtering, and applying filtering to generate a second output signal, using filters that include a singly terminated filter section with additional circuit elements to form a transmission frequency zero in the stopband frequency range.
