Title:
GRAY CODE COUNTER
Document Type and Number:
Japanese Patent JP3714875
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gray code counter, with which skip counting is enabled and the number of bit transitions in skip counting is two at all the time.
SOLUTION: This gray code counter is provided with a gray code counter 2 in the configuration of 5 bits for counting codes one by one and an output value converter 3 for skipping gray code data (Q0p to Q4p) outputted from the gray code counter 2 for a value subtracting '1' from the power of '2' and converting the result to gray codes (Q0 to Q4) corresponding to decimal counting corresponding to such counting so that the number of bit transitions in skip counting can become two at all the time.
