Abstract
A circuit for detecting and processing a signal from a sensing device such as a torque sensor is disclosed in which a first peak hold circuit detects a first peak value of an output AC signal of an oscillator and a second peak hold circuit detects the peak value of an output signal of a differential amplifier. The differential amplifier is connected across an output end of a bridge circuit for detecting a change in the output voltage from the torque sensor. A sign of a variable in the torque sensor is determined according to the first and second hold values derived from the first and second hold circuits. The magnitude of the variable of the torque sensor is detected according to the magnitude of the second peak value of the second hold circuit.
