<p>1. Pulse transmitter for converting the movement of a transmitter into a series of pulses dependent upon the direction of movement, having a sensor (1) which emits two series of pulses phase-shifted in respect of each other, the direction of the phase shift depending upon the direction of movement and the first series of pulses (A) being supplied to the clock input of a first JK flip-flop (2a) and inverted to the clock input of a second JK flip-flop (2b), and the second series of pulses (B) being supplied inverted to the J input of the first JK flip-flop (2a), characterized in that the second series of pulses (B), in non-inverted form, is supplied to the J input of the second JK flip-flop (2b) and in that the clock-independent reset input of the first JK flip-flop (2a) is connected with the non-inverting output of the second JK flip-flop (2b), and the clock-independent reset input of the second JK flip-flop (2b) is connected with the inverting output of the first JK flip-flop (2a), in which case the desired series of pulses for a first direction of movement is picked off at an output of the first JK flip-flop (2a).</p> |
