ABSTRACT OF THE DISCLOSURE A digital resolver processor measures the angle of a rotatable device. A resolver connected to the rotatable device generates sinu- soidal signals as a function of an excitation signal and of the resolver angle. A phase shift network receives the sinusoidal signals and generates leading and lagging phase shifted signals with a relative phase shift proportional to resolver angle. A counter is enabled by the leading signal and inhibited by the lagging signal so that the contents of the counter represents the relative phase shift, and thus, the angle of the rotatable device. The angular position of the resolver is limited so that the contents of the counter is maintained within a predetermined range in the absence of a fault condition of the resolver terminals. The contents of the counter is forced outside the predeter- mined range in response to short or open circuit conditions of the resolver terminals, so that misleading angle representations may be recognized as such.
