摘要：1. Pulse generator circuit for the production of actuating signals to change anelectrical value, with a) a rotatable adjustment wheel (ID) which a1) at two outputs with arotation per change of angle of rotation emits digital output pulses, from the pulsefrequency of which the actuating signal can be derived, with b) a multiplying circuitsubsequently connected to the adjustment wheel (ID) with a first counter (HZ1) which b1)at its counting input is loaded with the output pulses of the adjustment wheel (ID) andb2) at a stage input is loaded with the output signal of a first gate circuit (M1), wherebyb3) from the number of pulses which rest at the counting input (3) during the gate time(T1) predetermined by means of the gate circuit (M1) over the gate input (4), amultiplicator can be derived as change factor for the multiplication of the count of thefirst counter (HZ1) and thus for the multiplication of the output pulses of the adjustmentwheel (ID), and with c) a main counter (Z) which, for the derivation of the actuating signalfrom the output pulses of the adjustment wheel (ID) loaded with the multiplicator, c1) isattached to the output of the multiplying circuit, characterized in that b4) the firstcounter is loaded by means of a doubler circuit (EO) with the output pulses of theadjustment wheel (ID), in that d) the first gate circuit (M1) is a monostable tilting stage
and with its input by means of the doubler circuit (EO) is loaded with the output pulses ofthe adjustment wheel (ID), and in that e) a second, complementary output signal of thefirst gate circuit (M1) constructed as monostable tilting stage is conducted onto a resetinput (5) of the first counter (HZ1).
