A resolver is a type of rotary electrical transformer used for measuring degrees of rotation. It is considered an analog device, and has digital counterparts such as the digital resolver, rotary encoder. A rotating coil induces voltage in two stationary coils, and by comparing the phase of the signal in the two secondaries, the angle can be accurately determined. These systems were commonly used in mechanical control systems, for instance, counting the number of revolutions of a screw jack to move an aircraft's flaps to a specific extension.
