NCERT · Class 12 · Physics · Semiconductor ElectronicsWhich of the following gates is called a universal logic gate?
Step-by-Step Solution
NAND and NOR gates are known as universal gates because any basic logic operation (AND, OR, NOT) and hence any complex digital circuit can be implemented using only NAND or only NOR gates.
