, ALTERNATIVE LOGIC
GATES
Alternative Logic gates are the logic gates derived from the standard or
existing logic gates to enhance functionality of logic gates in general.


TYPES OF ALTERNATIVE LOGIC GATES

The following are types of alternative logic gates:

1. NAND gate (Not AND)

2. NOR gate (Not OR)

3. XOR gate (Ex-OR) (Exclusive-OR)

4. XNOR gate (Ex-NOR) (Exclusive-NOR)
