Abstract
A filter circuit includes a filter having an input and an output at which an output of the filter is provided, a step detector coupled to receive an input signal at the input of the filter and configured to detect a predetermined step in the input signal and to assert a bypass signal in response to detection of the predetermined step. A logic circuit is responsive to the bypass signal and configured to cause the input signal to be coupled to the output of the filter without filtering when the bypass signal is asserted.
