Abstract:
A method of determining a direction of rotation of a shaft is disclosed, as well as an integrated circuit chip that uses the disclosed method. The method includes receiving a first binary signal and a second binary signal from a transducer attached to the shaft, with the first and second binary signals being in quadrature. A present quadrant identification number, QID PRESENT , is determined as a two-digit binary number by left-shifting a value of the first signal and adding a value of the second signal. After a sampling interval has elapsed, the method sets a past quadrant identification number, QID PAST , to the value of said QID PRESENT , determines a new value of QID PRESENT  and calculates a value of a transition code using an equation that operates on QID PRESENT  and QID PAST . The method uses the transition code to determine a direction of rotation of the shaft.

Claim (Index 15):
The electronic device of  claim 14 , wherein the instructions, when executed by the processor, further cause the processor to, after the determination of the new value of QID PRESENT  but before the determination of the value of the transition code as a function of QID PRESENT  and QID PAST , determine whether a transition has occurred.
