Abstract: PURPOSE:To reduce the number of RAMs and to increase a processing speed, by inputting the predetermined bit binary data of the output of a synchro-digital converter to a control part, RAM for a higher rank table and RAM for a lower rank table. CONSTITUTION:The output data of a synchro-digital converter 1 is inputted to a control part 2, a higher rank table 3 and a lower rank table 4. The table 4 (or 3) inputs the output data corresponding to the lower rank 12-bits (or upper rank 4-bits) of 16-bits to an adder 5 and the output data of both tables are added to the adder 5 to be outputted as conversion output. In this case, for example, the lower rank table is constituted of RAM allotting 0-1023 at a pitch of 1 and the higher rank table is constituted of RAM allotting 1024-31744 at a pitch of 1024. By this method, for example, when input data corresponds to output data 2500, 2048 from the higher rank table and 452 from the lower rank table are added by the adder 5 to output 2500. Therefore, a table circuit can be constituted of the reduced number of RAMs.
