Abstract:
    A signal splitter (24) comprising an input (26) and a plurality of outputs (28,30) is provided, wherein alternate outputs (28) are connected to phase shifting devices (32). The phase shifting devices (32) comprise phase shifting transformers and introduce a phase shift of 180 DEG , so that noise components of alternate outputs (28) are in antiphase and cancel one another out almost entirely when the signals are summed. Also provided is a cable television network comprising a plurality of such signal splitters to ensure that noise ingress in upstream signals passing into the network is substantially reduced.
