Abstract
A disk mounted on a rotating shaft of an internal combustion engine has a signal generating segment which causes generation of a pickup signal having a leading and a trailing edge. The two different edges control different processes, as for example ignition processes of different ignition coils, fuel injection processes, or ignition processes during normal and starting operation. A basic counting value is counted down between two sequential edge signals in a counter. This is a speed-dependent value from which different countdown values for the next cycle are computed. To allow adjustment of the angle at which one process takes place without simultaneous adjustment of the angle at which the other process takes place, one or both of the edges of the segment from which the control signals are derived have slanted portions, so that movement of the pickup relative to the slanted portions will effectively cause a change in the angle at which a process is initiated.
