In an apparatus, method, and system for reducing interference with an
input signal to an FM receiver, a plurality of inputs are filtered by a
first stage of filters. The outputs are received by an interference
detector and further processed by a second filtering stage, an energy
calculation stage, and a comparator stage. A switch, responsive to the
outputs of the comparator stage, may output one of the first stage filter
outputs based on a first set of comparator outputs and may output an
interpolated value determined by the first stage filter outputs and based
on a second set of comparator outputs.
