Abstract
A signal splitter for reducing noise ingress and a cable television network incorporating such splitters. A signal splitter has an input and a plurality of outputs, where alternate outputs are connected to phase shifting devices. Prevention circuitry is provided for at least preventing the generation of intermodulation products in the phase shifting devices. The prevention circuitry is provided with a pre-connected filter in the form of a high-pass filter for stopping voltage peaks through reflection of the energy contained in the voltage peaks.
