Digital Electronics/Logic Operations
Logic Operation
[edit | edit source]- 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
[edit | edit source]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
[edit | edit source]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
[edit | edit source]Each Logic can be constructed from electronic components to form a circuit of a device called Digital Gates to perform the logic operation
