摘要：There is provided a position transducer () capable of accurately detecting an n-bit code by ABS detectors from one ABS track. When an INC value is under or over , signaloutput from each of the ABS detectors is binarized based on a threshlold and also based

on a threshold . First, an ABS value decider () decides that a bit is H when it has beenjudged as being H on the basis of both the thresholds and a bit is L when it is has beenjudged as being L on the basis of both the thresholds. When the INC value is under , alower bit has the same code as that of the deiced bit. So, the ABS value decider () decidesthat the lower bit is H or L. On the other hand, when the INC value is over , an upper bithas the same code as the decided code. Thus, the ABS value decider () decides that theupper bit is H or L. The ABS value decider () decides a yet-to-decide bit to be L when a bitadjacent to the bit is H, and H when the adjacent bit is L.
