Abstract

PURPOSE: To obtain an equivalent output without using synchronizing detection circuit and avert the decrease in SN ration owing to parasitic noise by sampleholding the detector outputs with the signals of the phases same as and perpendicularly intersecting with excitation signal and letting the signals obtained from a trigonometric function generator and the signals corresponding to both be inspection outputs.
