摘要：
The measurement of an a.c. signal is accomplished by feeding the signal through an a.c. amplifier having variable gain to a detector from which a d.c. signal characteristic is extracted indicative of its value. The d.c. signal is fed back to control the amplifier gain and maintain the level of the detector input within a limited range.
