  • Two methods, manual backing off and capacitor coupling (by cutting off the d.c. component) are usually used to measure a small transient signal superposed on a large electric current. The shortcomings of them are analysed and an automatic current backing off circuit with high accuracy is described in this paper. The response time of this circuit needed for the compensating a sudden change in the large electric current is less than 50 microseconds. The described circuit can be used for the time scale from 1....
