ABSTRACT:
An equalizer arrangement is used in a digital signal receiving system for the equalization of digital signals received in analog form and transmitted through an analog/digital converter, which have been distorted by a precursor and postcursor effects of previously transmitted or subsequent digital signals. The equalizer arrangement has a precursor equalizer followed by a postcursor equalizer connected with it. A compromise equalizer, which is connected upstream of the precursor equalizer, receives a sample value which is applied to it for each transmitted digital signal and is designed as a first-order filter with the following transmission function: ##EQU1##
