Question 163 of 209

Name the logic gate equivalent to the diagram attached

A$NAND$B$AND$C$NOR$D$OR$

Show answer and solution▾

Answer: (C) $NOR$

Let's assume that when the path is short, the state is called state $1$ and when it is open, the state is called state $0$.
Depending up on whether the path is short or not in the circuit, the following table can be obtained: $A$ $B$ $Out$ $1$ $1$ $0$ $1$ $0$ $0$ $0$ $1$ $0$ $0$ $0$ $1$ The above table is similar to the truth table corresponding to $NOR$ gate. Hence, the circuit indicates a $NOR$ logic gate.
