Abstract
An electrical circuit for shaft torque measuring systems of the type having a transducer producing an electrical signal representing shaft torque and a brush and slip ring assembly providing an output connection for the electrical shaft torque signal includes an operational amplifier having the electrical shaft torque signal connected across an inverting input terminal and an output terminal with a capacitor providing negative feedback between the inverting input and output terminal and a resistor connected in series with the inverting input terminal to form with the capacitor a low pass filter such that resistance variations and circuit interruptions in the electrical shaft torque signal producing circuit do not adversely effect the output signal.
