  • Patent number: 7679471
    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.
    Type: Grant

  • Publication number: 20020191111
    Abstract: The invention relates to a communication system 1, wherein the communication system 1 comprises a cable transmission network 3 with several terminal connecting points 6 provided with high-frequency transmission and/or receiving means. The cable transmission network 3 furthermore comprises signal processing means for processing high-frequency signals that can be transported via the cable transmission network 3. The signal processing means comprise prevention means for at least partially preventing the generation of intermodulation products in the signal processing means. The prevention means comprise a pre-connected filter, such as a high-pass LC filter, for stopping voltage peaks through reflection of the energy contained in the energy peaks.
