Claim 9:
10. The load control device of claim 9 wherein the filter circuit comprises a first capacitance in electrical parallel with a switch coupled to a second capacitance;
wherein the control circuitry selectively transitions the switch between a CONDUCTIVE state and a NON-CONDUCTIVE state; and
wherein to selectively transition the filter circuitry to the high capacitance first impedance state responsive to the determination that the duty cycle of the controllably conductive device falls within the first duty cycle range of from 25% to 75% the control circuitry to:
selectively transition the switch to the CONDUCTIVE state such that the first capacitance and the second capacitance are coupled in electrical parallel with the controllably conductive device.
