Digital Electronics/Logic Operations

Logic Operation

 * Logic BUFFER perform a logic operation on a input . Output is the same as Input
 * Logic NOT perform a logic operation on a input . Output is the invert of Input
 * Logic AND perform a logic operation on two input to yield a result at the output. Output is High only when both Inputs are High
 * Logic OR perform a logic operation on two input to yield a result at the output. Output is Low only when both Inputs are Low
 * Logic XOR perform a logic operation on two input to yield a result at the output. Output is Low only when both Inputs are the same and Output is High only when both Inputs are different

Digital Logic Equation
If A and B is Input and Y as Output then
 * Logic BUFFER → Y = A
 * Logic NOT → Y = NOT A
 * Logic AND → Y = A AND B
 * Logic OR → Y = A OR B
 * Logic XOR → Y = A XOR B

Digital Truth Table
The logic operation of any logic above can be summarized in a table called a truth table.

If High is 1 and Low is 0 then

Digital Gates Construction
Each Logic can be constructed from electronic components to form a circuit of a device called Digital Gates to perform the logic operation
