Abstract
An electrical circuit device comprises an integrating amplifier arrangement that provides a circuit output signal in response to an input signal from a differential amplifier. The differential amplifier receives at one of its input terminals the circuit input signal and at its other input terminal the circuit output signal. The circuit limits its output signal to change at less than a predetermined rate, and the device is particularly useful in a pendulum unit of a gyroscompass, where the rate limitation can be arranged such that the compass does not respond to acceleration due to motion of the craft or vehicle in which the compass is mounted.
