Schaltungsanordnung zur Erzeugung von ImpulsenCircuit arrangement for generating pulses
Die Erfindung betrifft eine Schaltungsanordnung zur Erzeugung von Impulsen variabler Amplitude und Polarität.The invention relates to a circuit arrangement for generating pulses of variable amplitude and polarity.
Aufgabe der Erfindung ist es, eine möglichst einfach aufgebaute und sicher arbeitende Schaltungsanordnung zur Impulserzeugung zu schaffen.The object of the invention is to provide a structure that is as simple as possible and to create safely operating circuitry for generating pulses.
Gelöst wird diese Aufgabe dadurch, daß eine Addierstufe vorgesehen ist, deren erster Eingang über einen ersten Schalter mit dem einen Pol einer Spannungsquelle und deren zweiter Eingang über einen zweiten Schalter mit dem anderen Pol der Spamiungsquelle verbunden ist, daß die beiden Schalter mit gleichzeitig auftretenden Schaltimpulsen einer Inipulsquelle gesteuert sind und daß das Potential einer der Pole regelbar ist, so daß am Ausgang der Addierstufe die Impulse variabler Amplitude und Polarität abnehmbar sind.This object is achieved in that an adding stage is provided is whose first input via a first switch to one pole of a voltage source and whose second input via a second switch to the other pole of the spam source is connected that the two switches are controlled with simultaneously occurring switching pulses of an Inipulsquelle and that the potential of one of the poles can be regulated so that the pulses of variable amplitude and at the output of the adding stage Polarity are removable.
Hierdurch ist ohne großen Aufwand an.Schaltungselementen eine Impulserzeugerschaltung geschaffen, welche es gestattet, durch Verändern nur einer Größe die erzeugten Impulse in Amplitude und Polarität zu ändern.As a result, circuit elements can be connected without much effort Pulse generator circuit created which allows, by changing only one size, the generated pulses in amplitude and change polarity.
Die Erfindung soll nunmehr anhand eines in den Figuren 1 und 2 dargestellten Ausführungsbeispieles näher erläutert werden, wobei
nur die zum Verständnis der Erfindung notwendigen Teile dargestellt sind.

Die erfindungsgemäße Impulserzeugerschaltung besteht aus einer Addierstufe 1, deren erster Eingang 2 über einen Schalter 3 (z. B. einen elektronischen Schalter in Porin eines Schalttransistors) an den Pluspol 4 einer Spannungsquelle angeschlossen ist. Der zweite Eingang 6 der Addierstufe 1 ist über einen zweiten Schalter 7 mit dem Minuspol 8 der Spannungsquelle verbunden. Das Potential am Minuspol 8 ist veränderbar (z, B. durch ein in der Fig. 1 nicht dargestelltes Potentiometer). Den Schaltern 3 und 7 werden gleichzeitig auftretende Schaltimpulse a von der Schaltimpulsquelle 9 zugeführt. Dadurch werden die Eingänge 2 und 6 der Addierstufe 1 kurzzeitig mit den Polen 4 und 8 der Spannungsquelle verbunden. Am Eingang 2 entsteht daher die Impulsfolge b, deren Impulsamplitude dem konstanten Potential am Pluspol 4 entspricht, und am Eingang 6 die Impulsfolge c, deren Irapulsamplitude variabel ist. Am Ausgang 11 ist dann die Impulsfolge d abnehmbar, welche in Amplitude und Polarität durch Änderung des Potentials am Minuspol 8 variabel ist.The pulse generator circuit according to the invention consists of a Adding stage 1, whose first input 2 is via a switch 3 (e.g. an electronic switch in the porin of a switching transistor) is connected to the positive pole 4 of a voltage source. The second input 6 of the adder 1 is via a second switch 7 connected to the negative pole 8 of the voltage source. The potential at the negative pole 8 can be changed (e.g. by a potentiometer not shown in FIG. 1). Switches 3 and 7 receive switching pulses that occur at the same time a supplied from the switching pulse source 9. This means that inputs 2 and 6 of adder 1 are briefly connected to poles 4 and 8 connected to the voltage source. At the input 2 there is therefore the pulse train b, the pulse amplitude of which is constant Potential at the positive pole 4 corresponds, and at the input 6 the pulse sequence c, the pulse amplitude of which is variable. At exit 11 the pulse sequence d can then be removed, which is variable in amplitude and polarity by changing the potential at the negative pole 8 is.
