Movable tap finite impulse response filter

摘要

An integrated circuit configured to perform finite impulse response filtering on a signal transmitted via a communication channel, the integrated circuit including an encoder and a plurality of filter stages. The encoder is configured to generate a logic signal corresponding to the signal transmitted via the communication channel. The plurality of filter stages is configured to filter the logic signal. Each of the plurality of filter stages includes a respective delay element. Each of the respective delay elements is configured to delay a corresponding portion of the logic signal. Two or more first delay elements of the plurality of delay elements are configured to apply a fixed delay. A second delay element of the plurality of delay elements is configured to apply a variable delay that is based on a signal strength of the corresponding portion of the logic signal.
