Abstract
An arrangement for measurement demodulation and modulation error measurement of a digitally modulated receive signal, which has a receive filter and a following demodulator for error compensation and for determining the ideal symbol samples. The measuring signal that is filtered in a reference filter and weighting filtered is then evaluated in a following evaluation circuit. The output signal of the demodulator is fed via a measuring filter to the evaluation circuit and the weighting filter function is formed by cascaded filter functions of the receiver filter and measuring filter.
