Abstract:
1. A method of making a filter assembly, the method comprising: disposing an electrically conductive input member on a substrate; disposing an electrically conductive output member on the substrate; disposing a plurality of band filters on the substrate, wherein each band filter is structured to pass or stop oscillatory electrical signals in a respective frequency band; disposing a plurality of connections on the substrate in one-to-one correspondence with the band filters, wherein the connections are structured such that every connection is disposed in an electrically non-conductive open configuration or such that every connection is disposed in an electrically conductive closed configuration; and structurally modifying at least one of the connections from the electrically open configuration to the electrically closed configuration or from the electrically closed configuration to the electrically open configuration, wherein, at least upon structurally modifying at least one of the connections, a transmission path for oscillatory electrical signals is defined between the input member and the output member, through which transmission path oscillatory electrical signals in at least one said frequency band is attenuated or blocked from passing from the input member to the output member.
