Question -
Answer -
(a) A and B arethe inputs and Y isthe output of the given circuit. The left half of the given figure acts as theNOR Gate, while the right half acts as the NOT Gate. This is shown in thefollowing figure.
Hence, the output of theNOR Gate =
This will be the input forthe NOT Gate. Its output will be
= A + B
∴Y = A + B
Hence, thiscircuit functions as an OR Gate.
(b) A and B arethe inputs and Y isthe output of the given circuit. It can be observed from the following figurethat the inputs of the right half NOR Gate are the outputs of the two NOTGates.
Hence, the output of the given circuit can be written as:
Hence, this circuit functions as an AND Gate.
