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 3):
The method of  claim 1 , further comprising, in responsive to determining that the transition code is not valid, performing an invalid transition code routine.
