System for monitoring, measuring and evaluating position encoder signals from radar, has logic circuits measuring number of pulses, where measured value is compared with expected theoretical value

摘要

The system has logic circuits measuring the number of pulses generated by an oscillator pattern contained in the half-periods of the pulses from the position encoder over a full cycle. The measured value is compared with expected theoretical value, and a profile of the allowed deviations is established to evaluate the state of the pulses generated by the encoder.
