#158297 - negartive and positive logic ... |
.. is defined by what level "TRUE" is
thus, for instance when 'high' is true (positive logic) an AND is defined by two highs (TRUEs) in equals TRUE (high) out conversely, when 'low' is true (negative logic) an OR is defined by any low (TRUE) in equals TRUE (low) out thus the truth table is the same for the two above a b y l l l l h l h l l h h hErik |

| So what?? | 01/01/70 00:00 | |
| Language??? | 01/01/70 00:00 | |
| deMorgan ... | 01/01/70 00:00 | |
| deMorgan states pos AND = neg OR | 01/01/70 00:00 | |
| Is there a contradiction here? | 01/01/70 00:00 | |
| NO!, it is a negative NOR | 01/01/70 00:00 | |
| I don't follow ... | 01/01/70 00:00 | |
| negative logic / means TRUE | 01/01/70 00:00 | |
| / means NOT | 01/01/70 00:00 | |
| Negative input NOR = Negative OR | 01/01/70 00:00 | |
| I have never heard of | 01/01/70 00:00 | |
| NAND and NOR fuzzy? | 01/01/70 00:00 | |
| nope | 01/01/70 00:00 | |
| I beg to differ | 01/01/70 00:00 | |
