Abstract
IN the course of an investigation into servo circuits and self-balancing systems in general I had opportunity to examine the effect of reactive elements in the negative feedback networks of electronic amplifiers on the response characteristics of current measuring instruments. Detailed mathematical analysis revealed a number of facts which make it appear probable that a reactive feedback circuit can be used as an alternative to other negative feedback circuits in galvanometers, such as the twin-coil meter1 or the mirror-and-photocell instrument2,3,4, without interference with the mechanism of the instrument itself.
