So I am well familiar with how bi-state logic (with 0s and 1s) works in gates. 0+0=0; 0+1=1+0=1+1=1 etc.(adsbygoogle = window.adsbygoogle || []).push({});

What happens if an input to a gate is neither 0 nor 1, but has an high-impedance value? Will it disable the logic gate from working? Will the logic gate simply ignore that input? Anyone have any clues? Perhaps it depends on what series chip one is using?

Really appreciate it! Thanks!
