Rectangular pulse generator with digital logic circuit - derives time symmetrical pulses applied to balancing circuit making them amplitude symmetrical

摘要

The limited number of generated pulses are time and amplitude symmetrical. They are derived from a time asymmetrical rectangular AC voltage containing a DC component. A digital logic circuit (FF1, G) derives time symmetrical pulse trains of specified duration from the rectangular time symmetrical AC voltage with a DC component, and from a control signal switching this AC voltage on and off. These pulse trains are applied to an electronic balancing circuit in which they alternately switch on two specified, equal voltages of opposite polarities.
