Q5- What is the output of the following circuit?
Ans: This circuit may look simple to you as one has to just evaluate every NOR gate and get the final output but I say it is even simpler than this. Let’s analyze the truth table of NOR gate:
And we see that even if only one of the 2 inputs is 1 then we need not find out the other input and we can get the output.
As in the above circuit we have one input as 1 to the last NOR gate so we can say that output of the above circuit is ‘0’ without calculating the outputs of other NOR gates.
