Abstract: A circuit for producing a pulse succession of long duration from several mutually independently produced synchronous pulse successions of shorter duration in which the output signal is derived as a logical function. Each of the pulse successions of shorter duration is produced by a separate generator and the pulse succession program of each of the generators is determined by a common information carrier, in particular a punched strip. A memory is interposed to take the information which is emitted separately by the information carrier for each of the generators and controls the respective generator. A sensing device is provided for the information carrier to respectively evaluate a portion of the information contained therein, the sensing device being connected to a series-parallel converter having storage facilities for the parallel result to effect adjustment of the individual generators.
