Which of the following logic gates is an universal gate? [2005]
Text Solution
Verified by ExpertsThe correct answer is:
B
The NAND gate and the NOR gate can be said to be universal gates since combinations of them can be used to accomplish any of the basic operations and can thus, produce and inverter, an OR gate or an AND gate. The non‐inverting gates do not have this versatility since they can’t produce an invert.
