Introduction To Logic Gates
Logics Gates are the building blocks of digital circuit.
They performed basic logical function on binary inputs
(0 and 1).
Basic Logic Gates
1. AND GATE:
 Symbol:D-Shape with two inputs and one
output.
Output is 1 only if both inputs are 1.
 Boolean expression :A.B
2. OR GATE
 Symbol:curved shape with two inputs and one
inputs
Output is 1 if at least one input is 1.
 Boolean expression : A.B
3. NOT GATE
 Symbol: Triangle with a circle at the tip.
 Has one input and one output.
Output is opposite of the input.
 Boolean Expression: AorA`
Universal Gates
1. NAND Gates:
 Combination of AND + NOT
Output is 1 if inputs are different.
 Boolean Expression: ~(A.B)
2. NOR Gate
 Combination of OR +NOT.
Output is 1 if both are 0.
 Boolean Expression: ~(A+B)
Exclusive Gate
1. XOR Gate(Exclusive OR ):
Output is 1 if inputs are different.
 Boolean Expression:A B
⊕
2. XNOR (Exclusive NOR ) Gate
 Output is 1 if inputs are the same.
Boolean Expression:~A B
⊕
Applications of logics gates
 Uses.
 Arithimatic logics unit.
 Digital Electronics.
 Computers.
 Embedded Systems.
Conclusion
Logic gates are they basic building blocks of
digital circuits.They process binary inputs to
produce specific outputs ,helping run
devices like computers and calculators.
