Xand logic gate
Archive: 5 posts
| Yeah, I need and Xand gate... For... Something. I have no idea how to build one lol. Either that, or a way to make a XNor gate. Help! XD (an Xand gate is 'on' when no imputs, and all imputs are on.; also a NOT-Xor) | 2010-10-05 02:30:00 Author: Fishrock123  Posts: 1578 |
| You can only do it the long way. Use two AND gates and an OR gate. One of the AND gate is on if all of the inputs are on, the other is on if none of the inputs are on. Then the output from the AND gates are connected to an OR gate. There will be many different ways to build a XAND switch, but it will always include three magnetic switches (2X AND and an OR). A XNOR gate will also have three magnetic switches. If you're still having problems with it add me and I'll build one for you. | 2010-10-05 18:10:00 Author: fluxlasers  Posts: 182 |
| Eh, I think I figured it out last night. I should just be able to reverse-output Incinerator's simple Xor. (1 switch, 2 moving parts.) Then again, I'm not 100% sure if I actually need am Xand anymore, so, yeah. | 2010-10-05 18:40:00 Author: Fishrock123 Posts: 1578 |
| (an Xand gate is 'on' when no imputs, and all imputs are on.; also a NOT-Xor) For a two input gate, that's more commonly known as XNOR, in which case simply inverting the output of an XOR will work. For more than two inputs, there isn't really a common name for the function you're describing, but feeding all inputs into both a NOR and an AND gate, then feeding the outputs of those two gates into an OR gate should do the trick. | 2010-10-05 18:59:00 Author: Aya042  Posts: 2870 |

Should only be two imputs, atleast in the current state of my contraption. | 2010-10-05 20:13:00 Author: Fishrock123 Posts: 1578 |
