Question

When the input of a two input logic gate are 0 and 0, the output is 1. When the inputs are 1 and 0, the output is zero. The type of logic gate is
  1. XOR
  2. OR
  3. NOR
  4. NAND

A
XOR
B
NAND
C
OR
D
NOR
Solution
Verified by Toppr

The truth table for a NOR gate is as given.
It is a combination of OR and NOT gate.
The output out of an OR gate for both inputs 0 is 0.
The NOT gate would turn it into 1.
The output out of an OR gate for inputs 1 and 0 is 1.
The NOT gate would turn it into 0.

Therefore,the logic gate is NOR gate.
