Abstract: In a transducer signal processing system wherein the output signal generated by a transducer (14) includes a nearly d.c., relatively large amplitude drift component (12), a higher frequency end point, data component (10) and a high frequency noise (hash) component (11), the drift and hash components are substantially eliminated by supplying the composite transducer output signal to a pair of parallel integrator circuits (28, 30) having different integration time constants. The faster integrator (28) passes the drift and data signal components, while attenuating the hash component, whereas the slower integrator (30) passes the drift component and attenuates the data and hash components. The output of the slower integrator (30) is subtracted from the output of the faster integrator (28) to provide a resultant signal containing essentially only the transducer data component.
