Abstract:

It is shown that for the analog signal output of digital devices one mostly uses impressed currents formed by feedback operational amplifiers. The paper deals with the calculation of such circuits, in particular the wiring for current signals and the arising coupling between several operational amplifiers one with the other. The influence of the errors due to the coupling is determined, the treatment being carried out in the control engineers way. Author
