Beschreibung
Zusammenfassung:	A power driver, diodes and a low pass filter are coupled to the resistance load through terminals. A first feedback voltage is derived from a third winding of the transformer. The voltage developed across this winding is supplied to a compensation circuit and a peak detector. This compensates for voltage dropped across the diodes. The peak detector outputs a voltage directly proportional to that dropped across the load. A high pass filters drives the AC component and the low pass filter of the CD component.
