Abstract

A method and arrangement for bit-synchronizing a &Sgr;&Dgr;-modulator uses a pre-filter to filter an incoming single bit bitstream. One or more of the integrator states of the &Sgr;&Dgr;-modulator are corrected by a signal which is calculated from the incoming bitstream and at least one of the pre-filtered input signal and the output bitstream of the &Sgr;&Dgr;-modulator.
