The registers storen-bit words and are stepped by pulses from generator 4. A counter 7 is incremented after each n stepping pulses, the counter output being compared at 6 with an address signal at 9 representing a particular word position in the cyclic store. When the equality is found the word at the position represented by the address at 9 is in register Srm. At this instant the comparator output prevents stepping pulses from generator 4 reaching counter 7 and the registers Sr. If now read-out pulses are applied to input 8 the content of Srm is read out bit-by-bit to output 2.
