ABSTRACT An absolute encoder is arranged by a first memory 23 for storing thereinto an absolute value signal which is produced by an absolute value signal producing section 6 every constant time period; a second memory 24 for storing thereinto an absolute value signal which has been produced in one-preceding time period with respect to a time period of an absolute value signal entered into the first memory 23; a comparing/calculating section 25 for comparing the absolute value signal stored in the first memory 23 with the absolute value signal which has been produced in the one-preceding time period and has been stored in the second memory 24 so as to calculate an increase/decrease amount; a dividing process section 26 for dividing the increase/decrease amount in an equal rate within a producing time period of the absolute value signal; and an interpolated absolute value signal producing section 27 for reading the absolute value signal which has been produced in the one-preceding time period, and thereafter, for adding/subtracting the divided increase/decrease amount in a stepwise manner with respect to the read absolute value signal. As a consequence, both the absolute encoder and an absolute value signal producing process method thereof can be provided, which can produce a continuous interpolated absolute value signal which does not depend upon an absolute value producing time period, a control time period of a motor control apparatus, and a transfer method.
