非门(NOT Gate): F(A) = not A 异或门 (XOR Gate): F(A, B) = AB'+A'B 同或门 (XNOR Gate): F(A, B) = AB'+A'B 4、双输入逻辑门 双与门 (AND-AND): F(A, B, C, D) = AB+CD 双或门 (OR-OR): F(A, B, C, D) = A+B+C+D 与或非门 (NAND-OR): F(A, B, C,...
如果 XNOR Gate 的输入不同,则其输出为 0 (LOW)。 如果A 和 B 是 XNOR Gate 的输入,Y 是它的输出,那么 XNOR Gate 的逻辑表达式是 Y = A ⊕ B。 或非门的逻辑符号和真值表如下所示。 结论 我们已经了解了逻辑门的基础知识,包括 NOT、OR、AND、NAND、NOR、XOR、XNOR 和 Buffer 以及它们的逻辑表达式...
aWhen a NOT gate is combined with an AND gate or an OR gate, it is called a combination logic gate. A NOT-AND gate is called a NAND gate, which is an inverted AND gate. Mathematically, the operation of a NAND gate is A.B=C. 当没有一个门与没有结合和门或者或门时,它称组合逻辑...

Proof of concept of directed OR/NOR and AND/NAND logic circuit consisting of two parallel microring resonators We propose and demonstrate a directed OR/NOR and AND/NAND logic circuit consisting of two parallel microring resonators (MRRs). We use two electrical signa... Yonghui,Tian,Lei,... -...
The output of the first e-OR gate is connected to the input of the second, the second's output to the third and so on to the last e-OR. Four NAND-gates are connected to pairs of the inputs. The outputs of all the NAND-gates and the last e-OR gate are coupled over diodes to...

TheNAND gateoperates as an AND gate followed by a NOT gate. It acts in the manner of the logical operation "and" followed by negation. The output is "false" if both inputs are "true." Otherwise, the output is "true." NAND gate ...
