  • Gray code counter
    Patent number: 4618849
    Abstract: A gray code counter is produced from a binary code counter by connecting each output of the binary counter to a "toggle" flip-flop. Each toggle flip-flop has a toggle input connected to its corresponding binary output. The output of each toggle flip-flop changes state (i.e. "toggles") only when its corresponding binary code bit makes a transition from a first level to a second level (i.e., it does not change state when its corresponding binary code bit makes a transition from the second level to the first level).
