Method for equalizing an input signal and equalization apparatus for equalizing an input signal

Abstract

A method for equalizing an input signal is described. The method includes the steps of receiving an input signal; sampling the input signal with a pre-defined sampling rate, thereby obtaining a sampled signal; applying a decimating filter to the sampled signal, which results in a decimated signal having a reduced sampling rate; and applying a digital filter to the decimated signal, thereby obtaining a filtered signal having an at least partially corrected frequency response. Further, an equalization apparatus for equalizing an input signal is described. The equalization apparatus comprises an input for receiving an input signal and an electronic circuit configured for sampling the input signal with a pre-defined sampling rate, applying a decimating filter to the sampled signal, and applying a digital filter to the decimated signal, thereby obtaining a filtered signal having an at least partially corrected frequency response.
