ABSTRACT:
A servo amplifier system includes first and second operational amplifiers, with the second amplifier having a low output impedance. A torque coil is connected directly from the output circuit of the first amplifier to the input circuit of the second amplifier free of any impedance elements which would tend to make the torque coil subject to frequency response variations. Various circuits are provided to feed back error signals from the output circuit of the second amplifier to the input circuit of the first amplifier. A test signal may be connected across torque coil to test the response of the accelerometer including the torque coil.
