Abstract
Rather than using the viscosity of dampening oil to establish the speed at which the movement of an air core instrument gauge moves, the speed is defined by programming speed data into memory of a microprocessor that controls the movement. When the microprocessor receives an input signal commanding the movement to move, it develops an output signal for operating the movement that is based both on the input signal and on the stored speed signal. The stored speed signal is used by the microprocessor as weight for a software filter used in development of the output signal.
