Which one of the following figures represent a NAND gate? i. A ii. B iii. C iv. D DI B C. Which logic gate does the following truth table belong to? i. Ex-NOR Gate ii. NAND Gate iii. EX-OR Gate iv. NOR Gate 1 0 B 0 0 0 1 1 1 0 1 1 0 D. Which logic gate does the following truth table belong to? i. Ex-NOR Gate ii. NAND Gate iii. EX-NOR Gate iv. NOR Gate 0 0 B 0 1 0 1 0 0 1 1 1 1 A E. What type of logic gate does this logic circuit configuration produce? I. NAND gate ii. NOR gate X = B + AB iii. EXOR gate iv. EXNOR gate F. The output of a NAND gate with three inputs, A, B, and C, is HIGH when: B i. A = 1, B = 1, C = 1 ii. A = 0, B = 0, C = 0 iii. A = 1, B = 1, C = 0 iv. A = 1, B = 0, C = 1 G. Identify the function generated by the logic circuit illustrated below. i. F=A F(A,B,C) ii. F= ABC iii. F = ABC iv. F = (A+B)C
