Abstract
The instrument described is a servo which provides an output proportional to the logarithm of the input over 4 decades. Use of a special four-decade exponential feedback potentiometer makes the accuracy and repeatability much better than that obtainable with the usual logarithmic amplifiers. A period trip circuit is part of the instrument.
