MATH 1505 Lecture Notes - Lecture 1: Xor Gate, Nand Gate, Nor Gate

8. We use transistors to construct gates, the diagram below represents the gate. Source Emitter Ground a. NOT b. AND c. OR d. XOR

2. Recall that an XOR gate is a digital logic gate that gives a true (1) output when the two inputs are different, and false (0) otherwise. An equivalent XOR function with inputs A and B can be implemented in Excel 2010 using the formula: a) = AND(OR(A,B), NOTAND(A,B))) b) =A<>B c) = NOT(NOT(A<>B)) d) EAND(NOT(AND(A,B)), OR(A, B)) e) All of the above x

5. The following truth table defines the B, and output X. digital logic gate with two inputs, A and X A B 100 0 1 | 1 0 1 1 0 a) NAND X b) NOR c) OR d) AND e) None of the above
