Abstract

An apparatus for readjustment of a sampling time in a radio receiver includes a component for determination of any sampling time error in a discrete-value received signal that emits a sampling time error signal. A filter arrangement is provided that includes a multi-rate filter that filters the sampling time error signal. A correction element receives the discrete-value received signal and the filtered sampling time error signal, and emits a discrete-value received signal whose timing has been corrected in accordance with the sampling time error.
