Abstract
A filter assembly includes an electrically conductive input member, an electrically conductive output member, and filter elements. Each filter element includes a connection disposed in an open or closed configuration, and a band filter, which may be a band-pass filter or a band-stop filter. A generic filter assembly is first manufactured having all connections in their open or closed configurations. A channel-selective filter assembly is then further manufactured by structural modification of one or more of the connections. Each connection of the channel-selective filter assembly is in its open or closed configuration independently of each other connection of each other filter element. Each frequency channel in a cable television (CATV) network, for example, is restricted or permitted by the channel-selective filter assembly.
