#156200 - nope Responding to: ???'s previous message |
Erik,
Is this what you are describing? ( http://www.8052.com/forum/read.phtml?id=156197 ) nope what you show is a negaive NOR (any true (low) in gives a false (high) out) a negative OR is any true (low) in gives a trie (low) out. negative logic is negative at both sides of the gate Erik PS I tend to recall that Michael Karas posted an excellent illustration of positive/negative logic a while ago |
