Abstract
PURPOSE: To improve the performance of detection, by avoiding the detuning through the addition of a simple phase correction circuit.
CONSTITUTION: The signal to the lower differential amplifying circuit DA2 being the switching section of the quadrature type detector circuit Q-DET is delayed for the phase than that of the signal to the tuning circuit (detection coil), by means of the capacitor C added as the phase correction circuit PC. Thus, consequently, the phase difference bwtween 3 and 2 can correctly be made to 90°.
