<p>The control has a circuit containing a flip-flop (12), an 01Dgate(13),twodifferentiators(5,11)andaclockpulse counter (9). The inputs of an up/down counter are connected to the output of the AND-gate and the count input also to the 01Dgateoutput.TheAND-gateinputisconnectedtotheoutput of a clock pulse generator or to the output of the flip-flop. The inputs of the flip-flop are coupled to the outputs of the clock pulse counter via the differentiators.</p> |
