DPHN. 7807 ABSTRACT A circuit arrangement for identifying a series of un- known code words having two different information contents as well as a starting signal preceding the code words in order to identify radio call numbers and channel commands in a radio telephony system. A first clock pulse generator; started by the received starting signals, applies clock pulse to a first storage device, which contains the code words of the first information content to be identified, and to a code converter. The code words, which are read-out in parallel one after the other from the first storage device, are converted into serial code words by the converter. These serial code words and the received unknown code words to be identified are compared, bit-wise with one another, in a comparator. The comparator starts a second clock pulse generator when the code words of the first information content are in agreement with the code words read-out from the first storage device. The second clock generator applies clock pulses to a second storage do- vice which contains code words of the second information content and these code words are also applied to a converter and then compared with the received unknown code words of the second information content. The code words which are found to be in agreement are stored in a third storage device which can activate a control circuit of a mobile radio telephony station.
