Abstract
An adaptive filtering arrangement for providing bit-synchronous, time-dependent filtering of a time-varying analog input signal taking the form of a time-dependent low pass filter including at least one adaptive resistive element that exhibits a varying resistance value as a function of a time. The time-dependent low pass filter uses as a 'control' input a modifying element responsive to a clock signal associated with the received signal for creating a time-varying control signal applied as an input to the adaptive resistive element. The time-varying control signal is created to be synchronous with a baud interval of a created output signal such that the instantaneous bandwidth of the time-dependent low pass filter is synchronous with the baud interval, exhibiting a relatively small bandwidth during a central portion of the baud interval and exhibiting a relatively large bandwidth during a transition from one baud interval to the next.
