Question

A NOR gate and a NAND gate are connected as shown in the figure. Two different sets of inputs are given to this setup. In the first case, the inputs to the gates are A = 0 , B = 0 , C = 0. In the second case, the inputs are A = 1 , B = 0 , C = 1. The output D in the first case and second case respectively are

In first case A = 0 , B = 0 ∴ Output of NOR gate, Y = A + B ​ = 1 This output is the input for NAND gate, i . e . , Y = 1 and C = 0 ∴ D = Y ⋅ C = 1 In second case A = 1 , B = 0 ∴ Output of NOR gate, Y = A + B ​ = 0 This output is the input for NAND gate i . e .. Y = 0 and C = 1 ∴ D = Y ⋅ C = 1
