Optimum Design of a Position Detection System with a Sinusoidal Perturbation Signal

In a paper by McVey and Chen [1] the effect of the amplitude of a sinusoidal perturbtion signal on the accuracy of a position detection system was presented. However, the amplitudes considered were chosen arbitrarily, and no optimum value was specified. This paper presents a method for determining an optimum amplitude for a sinusoidal or, for that matter, any other perturbation signal. In addition, the method may be used to eliminate certain functional forms of a perturbation signal from consideration for a given receptor geometry.
