ABSTRACT:
A circuit arrangement is disclosed for the summation of products formed from analog signals and digital coefficients. A multiplying digital-analog converter is provided having a reference input for receiving analog signals at successive points in time. A data input of the digital-analog converter receives digital coefficients assigned to the respective analog signals. A summation stage connected to output signals of the digital-analog converter integrates over a predetermined time period the output signals of the digital-analog converter representative of products of the analog signals and digital coefficients.
