ABSTRACT:
The device for electronically simulating a component position includes a first counter (40,42) which counts counter pulses (Zt) determined by respective occurrences of a periodic event marking respective component positions; a second counter (30) which, in response to occurrence of a first event (e2), starts a third counter (34) which counts at a counting rate faster than that of the second counter (30) so as to repeatedly run through a predetermined value range (Z') until occurrence of a subsequent event (e3) and which produces a basic clock pulse (Co) each time a final value (y) of the predetermined value range (Z') is reached; and a readjustment circuit (38) which produces the counter pulses (Zt) from the basic clock pulses (Co). In one embodiment on occurrence of the subsequent event (e3) the readjustment circuit (38) corrects the counter state (ZS) of the first counter (40,42) by forming a difference between a predetermined set value and the counter state (ZS) and feeding a number of high frequency correction signals (KS) equal to that difference into the first counter if the counter state is less than the set value or masks a number of counter pulses (ZT) equal to that difference if the counter state is more than the set value.
