Abstract
The present invention provides a signal filtering apparatus, which comprises a control circuit and a filter for receiving a transmitted input signal and generating an output signal. The filter comprises multiple filter taps for processing the transmitted input signal corresponding to different timings with different filter coefficients, respectively, to generate the output signal. The control circuit is configured to shrink at least part of the low-frequency-response filter taps having filter coefficients less than a predetermined value.
