Abstract
The electronic circuit device for analysis of a periodically repeating digital signal from a rotational position transmitter, which includes groups of events, each of which has a first and last event and at least one additional event between them, includes a first counter (10) for counting periodically generated pulses (t1) fed to it; a counting device (14) for counting the events in each group; a detecting device for the first and last event of each group; and a circuit device for feeding the periodically generated pulses (t1) to the first counter between the first and last event detected by the detecting device to form a counter count. This circuit device includes an and-gate (16) whose output is connected with the first counter (14) and whose inputs are connected to receive the periodically generated pulses (t1) and a first input signal (C1) between the first event and the last event of each group so that the and-gate (16) generates an output signal at its output between the first event and the last event of each group. A memory for storing the counter count of the first counter is also provided.
