Abstract
A method and apparatus for processing an applied signal. The applied signal is low pass filtered via a low pass filter having an input and an output, wherein the filter input and output are coupled to respective inputs of a selection device and respective inputs of a comparator. The comparator compares each of its inputs to one another and produces an output indicating which of its inputs has a lower amplitude. The comparator output is applied to a control input of the selection device such that the selection device will output the signal with the lower amplitude, either the applied signal or the low pass filtered signal.
