Abstract:
Upstream noise suppression circuits include a splitter and a combiner that are connected by first and second communications paths. An information signal removal circuit is provided on the second communications path and is configured to remove an upstream information signal therefrom. A phase shifter is also provided on the second communications path between the upstream information signal removal circuit and the combiner.
