Abstract
A system that provides a signal in an assigned time slot of a multi-time slot repetitive frame, the assigned time slot being determined by input data that changes only on occasion, includes a flywheel circuit for reducing the chance that intermittent errors in the data input may cause the signal to be provided in an incorrect time slot. The flywheel circuit includes a time slot counter synchronized to provide a zero count during the assigned time slot and to initiate an output signal whenever the zero count occurs. The timing of a particular count of the counter is compared to the timing of the signal from the system during each frame, and if the timing does not correspond in a predetermined manner for a predetermined number of consecutive frames, the counter is re-synchronized to the timing of the signal from the system.
