Abstract
Periodic digital signal samples of redundant sensed engine RPM signals are rejected for limit exceedance of known performance values, the nonrejected digital signal samples are each compared with a synthesized RPM equivalent signal to further reject any sample which differs from the synthesized value by more than a selected difference value, one of the nonrejected samples are then used for the engine RPM indication, and in the event that both samples are rejected the synthesized value is used.
