The decades of the modulo-10 counter according to the subject of the invention each have 10 simple counter flipflops (10 to 19), of which, in each decade counter state, only one counter flipflop is in each case in its left position. In this pulse counter, too, the counter flipflops are triggered alternately via two pulse lines (a and b). In this pulse counter, each decade is thus provided with a pulse reversing circuit (20), which has only a simple flipflop (30). The direct decade input (N) is only required in the special versions. <IMAGE>
