ABSTRACT:
An encoder signal processing device comprising an A/D converter converting a periodic analog signal, a memory storing position detection error information and a computing unit including a position data calculator which calculates position data from the digital data and an error correcting section which corrects the position data based on the position detection error information. The memory includes a first memory encoding position error data which is included in the position data by the use of the computing unit and storing a correction coefficient. A second memory decoding the position error data on the basis of the correction coefficient by the use of the computing unit and storing correction data for correcting the position data and error-containing position data generated on the basis of the encoded position error data.
