ABSTRACT:
To allow a displacement sensor to operate independently of changes in the excitation signal to the transducer, a demodulating circuit utilizing a single integrator is provided wherein comparison is made between the excitation signal and a reference signal, the comparison is used to adjust an output generating circuit which generates the output from the transducer. Advantageously, the output generating circuit can provide movement information from output of the transducer which include position, velocity and acceleration.
