Abstract
A circuit arrangement for determining a high-resolution angular position of a rotating member includes a sensor (7) for delivering relatively low resolution measuring signals which are applied to a circuit arrangement (11) for converting the measuring signals into a high-resolution indication of the angle of rotation. The circuit arrangement includes an evaluation circuit with a memory for storing high-resolution angle values, a controllable counter for controlling the memory and operating at two frequencies (f1 and f2), a comparator for comparing the output signals of the sensor and of the memory to change, via a regulating circuit, the counting rate of the counter from f1 to f2 in dependency on the result of the comparison. The count (i) of the counter represents a measure of the high-resolution angle of rotation.
