ABSTRACT:
A pulse generator for the generation of pulses which are synchronously associated with the movement of a mechanical part comprises a toothed element, the teeth of which run past a pick-up head, the pick-up head comprising a first winding fed by a carrier frequency, which produces a field which is modulated by the teeth of the element and a second winding in which a voltage is induced by the modulated field, the induced voltage is supplied to a phase discriminator which produces a pulse sequence having a keying ratio proportional to the relative phase position of the induced voltage and the carrier frequency and the pulse sequence is fed to an integration element which produces a voltage signal proportional to the keying ratio.
