Abstract

A method and an electro-mechanical arrangement for the generating and processing of electrical impulses for the setting or correction of an electronic digital display through the intermediary of an impulse generator. The impulse generator consists of an impulse transmitter and an impulse collector whereby, by means of the impulse emitter which evidences a plurality of impulse-generating elements, preferably arranged at uniform spacings in a circular path relative to a rotational axis, a plurality of electrical contacts are adapted to be closed in cooperation with the impulse-generating elements. The contacts of the impulse collector, generating mutually timewise displaced but still overlapping impulses whose frequency is proportional to the relative speed between the impulse transmitter and the impulse collector and whose phase position, in essence the phase lead and phase lag, is dependent upon the relative direction of rotation between the impulse transmitter and the impulse collector.
