Apologies if this is copied but I didn't find it with a quick search. Imgur Use a monostable circuit to unlock repeaters just long enough to take an on/off state from an input block. Imgur Pistons to cut switch all the inputs to off while the repeaters are unlocked to "drain" the signal out of the output. Imgur Compare the off/on state of the top line with a timing pulse on the bottom line using AND gates. Imgur Non-sticky pistons for the output.
