ABSTRACT:
An electronic circuit and method used in conjunction with transducers for eliminating noise signals which includes an AC source of excitation for first and second transducer coils, called pickoff coils located in first and second signal channels. Output from the pickoffs is supplied to detectors disposed in each of the signal channels. The detected pickoff output signals are filtered and connected to a summing circuit wherein the internally generated noise from the AC source appearing as common mode signals in both signal channels is cancelled and differential mode signals produced in said channels are added to produce an output.
