Abstract
An improved method and circuit for processing sensory input signals of the type obtained from Coriolis mass flow rate sensors and the like including differencing circuitry responsive to inputs received from two motion pick-up devices and operative to generate a 'different' signal which is directly proportional to the difference therebetween, integrator circuitry for reducing the frequency dependency by one order and shifting the phase of the difference signal by 90 degrees, summing circuitry responsive to the signals generated by the two pick-ups and operative to develop a 'sum' signal which is proportional to the sum thereof, and dividing circuitry for dividing the integrated difference signal by the sum signal to develop an output signal which is directly proportional to the rate of mass flowing through a conduit to which the two pick-up devices are attached.
