<P>PROBLEM TO BE SOLVED: To provide a transition detection circuit detecting a transition of a code signal in a simple configuration. <P>SOLUTION: A detection circuit detecting a transition of a Gray code that makes a transition by 1 bit includes a combination logic circuit outputting a signal that changes whether the number of 1s included in bits of the Gray code is even number or odd number; and a comparator circuit generating a transition detection signal that becomes valid when the output of the combination logic circuit is changed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
