Writing an expression using only NAND, OR, XNOR

问题 I have a 2-1 mux and I'm trying to write z = s'd0 + sd1 using only NAND , XNOR , and OR gates (not necessarily all of them). I tried simplifying it and what I ended up with is z = NAND(NAND(s', d0), NAND(s, d1)) , but I can't use NOT ( ' ), so is there a way to write NAND(s', d0) without the NOT ? 回答1: You can build NOT from NAND: NAND(X,X) == NOT(X) 回答2: NAND gate is an universal gate; you can use it to make any other gate. s' = nand(s,s) 回答3: Initial solution Full version of the solution

Should I eliminate inputs in a logic circuit design?

阅读更多关于 Should I eliminate inputs in a logic circuit design?

问题 Recently I had an exam where we were tested on logic circuits. I encountered something on that exam that I had never encountered before. Forgive me for I do not remember the exact problem given and we have not received our grade for it; however I will describe the problem. The problem had a 3 or 4 inputs. We were told to simplify then draw a logic circuit design for that simplification. However, when I simplified, I ended up eliminating the other inputs and ended up literally with just A I

I am creating a web-service which is aimed to simulate how do electronic circuits work. The project is not even in the Alpha stage yet. I am stuck with some important milestone of the project: when one tries to connect one component's pin to some other pin - the connection line should be built. First of all, the connection line was just a straight line, without almost any way to change it. Then it became somehow bended line with the possibility to add, move and delete points, which determined how the line is bended. And now it (connection line) is created using the A* algorithm. The
