A logic gate is an electronic device which performs the
implementation in boolean Function, it performs the logic operation of one or
two input with single output.
There are some logic gate which is given
1. AND
2. OR
3. NOT
4. NAND
5. NOR
AND Gate
A Logic AND Gate is a type of digital logic gate that has an
output which is normally at logic level “0” and only goes “HIGH” to a logic
level “1” when ALL of its inputs are at logic level “1”. The input state of a
LOGIC AND Gate only return LOW again when any of the input is at logic level 0.
In another word a logic AND gate, any low input will gate a low output.
The logical expression of given digital logic And is that
for logical multiplication which is denoted by the symbol(.)
A.B=Q
OR Gate
A Logic OR Gate is a type of digital logic gate that has an
output which is normally at logic level “1” and only goes “LOW” to a logic
level “0” when ALL of its inputs are at logic level “1”. The input state of a
LOGIC OR Gate only returns HIGH again when any of the input is at logic level
1. In another word a logic OR gate, any low input will gate a low output.
The logical expression of given digital logic And is that
for logical multiplication which is denoted by the symbol(+)
A+B=Q
NOT Gate
A NOT Gate is also called as the inverter Gate. A NOT gate
performs the logical operation of negation on the input. If the input is true
then the output is false and input is false then the output is true.
NAND Gate
The combination of NOT Gate & AND Gate is NAND Gate.
NOR Gate
The combination of NOT Gate & OR Gate is NOR Gate.
