Abstract : A signal processing system is disclosed that divides a broad band of input signals into separate channels separated by stopbands and permits operation in the crossover frequencies occuring at these stopbands. A triplexer separator receives and divides the broad band of input signals into a first, second and third band of signals, and sends them respectively to a first, second and third signal channel. The first and third signal channels are narrow bands which respectively occur at the lower and upper frequency end of the broad band of input signals. In normal operation the first, second and third signal channels separately and independently conduct their respective signals to a triplexer combiner, where they are recombined. However, if signal processing is planned at crossover frequencies in the stopbands of either the first or third signal channel, the first or third band of signals can be directed into the second signal channel to permit such operation.
