DIGITAL LOGIC

Introduction

In this chapter, based on our knowledge what are we learn during lecture and lab session. We are looking for Boolean algebra, truth table, Logic gate and Karnaugh map.

1. Boolean Algebra- Allow all the variable and operator to have only one possible value, which is 0 and 1.
   
   
2. Truth Table-The relationships of input and output can be specified by the truth table.
   
   
   
3. Logic gate with the truth table-Logic gate is an electronic circuit that combines with digital signal according to the Boolean algebra. The type of logic gate is AND, OR, NAND, NOR gate.
   
   
        >The AND gate
           - AND gate is the logic circuit that perform AND operation on input circuit.
                  - Performed by multiplication of 1 and 0.
                  
                          
   
   
   
   
        >The OR gate     
           -OR gate is a produces an output of 1 either the input is 1 or 0.
   
                          
4. 
   
   
   
        >The NAND gate
                 - NAND gate is the combination of NOT-AND on using the AND function.
   
                        
        >The NOR gate
           - NOR gate is the combination of NOT-OR on using the OR function
   
                        
   
   
   
5. Karnaugh Map
   -From Boolean expression, first step to do the karnaugh map is build the truth table.
