ABSTRACT Diversity reception techniques are known in radio communication systems. When reception is switched from one propagation path to another an instantaneous signal interruption is caused at the receiver output which is highly undesirable in the case of digital signal transmission. The present invention alleviates this problem by providing a digital signal gate switch for selecting one of a plurality of digital signals and a clock signal gate switch for selecting one of a plurality of clock signals extracted from the respective digital signals. A delay circuit delays the clock signal selected by the clock signal gate switch. A control signal read-out circuit is arranged to be fed with the output of the delay circuit to read out a switching control signal, separately fed to the control signal read-out circuit so that the digital signal and clock signal gate switches are contro- lled simultaneously by the output of the control signal read-out circuit.
