Abstract

See full text

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.
