摘要： A method and system for generating a position dependent output control signal. The position of a rotating machine, such as an internal combustion engine, is sensed and a corresponding position signal is generated. The position signal is processed to obtain the position dependent output control signal including a first control signal and a second control signal. The first control signal represents a sector of the rotating machine, and the second control signal represents the absolute position within the sector.
