<P>PROBLEM TO BE SOLVED: To adjust the signal level of each rotation signal of a secondary side and to facilitate an accuracy improvement of the signal, by adjusting the signal level of a primary side signal by the use of the rotation signal obtained from a rotation detector. <P>SOLUTION: The interface circuit is constituted to adjust the signal level of the rotation signal (K×sinθ×F(t), K×cosθ×F(t)) by adjusting the signal level of the primary side signal (F(t)) which is an excitation signal of the rotation detector (101) by the use of the rotation signal (K×sinθ×F(t), K×cosθ×F(t)) to be obtained from the rotation detector (101). <P>COPYRIGHT: (C)2013,JPO&INPIT |
