Abstract
A filter of an adjustable frequency response comprises a plurality of filters having a plurality of distinct frequency responses, respectively. These filters receive a common input signal and generate a plurality of intermediate signals, respectively. A multiplexing circuit is used to select one of these intermediate signals as a filtered signal. The multiplexing circuit is controlled by a control signal that is related to a state of the filtered signal.
