Q1:

The inputs A, B, C of the given figure are applied to a 3 input NOR gate. The output is

A HIGH from 4 to 0

B LOW from 0 to 4

C HIGH from 0 to 1 and LOW from 1 to 4

D LOW from 0 to 2 and HIGH from 2 to 4

ANS:C - HIGH from 0 to 1 and LOW from 1 to 4

NOR gate gives high output if all inputs are Low. For all other combinations of inputs, output is Low.
