Boolean algebra
- Boolean algebra is a tool for the analysis and design of digital system
- In this Algebra, there is no fraction, no negative number, no square root, etc
- when the number of variables is less (1,2,3)
- It is preferred when output is 0 or 1
K-Map
- when number of variables 2,3,4,5(up to 5)
- It is preferred when output is 0,1 or don't care
Tabulation method:
When number of input variables are more use Tabulation method
Laws of boolean Algebra:
some axioms:
AND operation OR operation Not Operation
0.0=0 0+0=0 0'=1
0.1=0 0+1=1 1'=0
1.0=0 1+0=1
1.1=1 1+1=1
