Abstract

PURPOSE:To make a pulse generator unnecessary by a method wherein a clock pulse similar to the pulse generator is prepared using a logic circuit to detect a digital angle. CONSTITUTION:A certain angle is divided by the smallest predetermined unit angle, and a clock pulse obtained by dividing a standard pulse f0 of a standard pulse generating circuit 13 by such the value as has been obtained above is prepared with a dividing circuit 14. This is followed by obtaining the AND 15 of an output f0/n and the output p0 of a standard angle detector 12 interfaced with the axis of rotation 11 to count 16 the value. Then the counted value C1 is ratched in every one cycle of the output p0 to output the counted value C1. The output CP' of fo/C1' is obtained from this output C1' using a dividing circuit 18 and the AND 19 of the output CP' and a detecting angle pulse Ptheta is obtained. The output obtained is counted by a counter circuit 20 in order to detect a digital angle.
