ABSTRACT:
An inductive (“L”)-capacitive (“C”) filter bank has application for use in a television receiver. The LC filter includes inductors configured in at least one inductive (“L”) bank, and capacitors configured in at least one capacitive (“C”) bank. The inductors and capacitors are selectively enabled so as to configure an LC filter with at least one inductor from the L bank and at least one capacitor from the C bank. A combination of inductors and capacitors are selected through the semiconductor switches so as to maximize a Q factor for the LC filter.
