Abstract
The input to an integrator is controlled by a logic circuit to reduce tracking errors caused by changes in acceleration. In one embodiment, the logic circuit obtains the derivative of the input signal and multiplies it with the input signal. The input signal is fed to the integrator through a switch which is closed when the product of the input signal and its derivative is positive, and which is open when the product is negative.
