Abstract
A shaft, the angular position of which is to be detected, equipped with a notched disk one tooth of which has been removed. A position sensor detects the passage of the teeth for a Schmitt trigger with its output connected to the inputs of two monostable multivibrators, to the up-down counter input of a counter, to one input of an AND gate and to the inputs of logic circuits. The held output of the counter is connected to an input of a type D flip-flop connected at its output to the second input of the AND gate.
