Basic Logic Gates

Basic gate

# AND gate/ Logical AND

→It is an electronic circuit used to perform logical multiplication(or AND operation) which is denoted by dot operator(.). So, its Boolean Expression is "A.B". It produces high output (1) when both the input are high, otherwise produces low output. 





# OR gate/ Logical OR
→It is an electronic circuit used to perform logical addition(or OR operation) which is denoted by plus operator(+). So, its Boolean Expression is "A + B". It produces low output (1) when both the input are low, otherwise produces high output. 
 




# NOT gate/ Logical NOT
→It is an electronic circuit used to perform logical complement(or NOT operation) which is denoted by single quote operator( ' ). So, its Boolean Expression is A'/B'. It produces high output if the input is low and vice-versa.
