Fundamentals of Logic
Boolean Algebra
Used to combine binary digits
Commutative
A + B = B + A
A.B=B.A
Associative
(A + B) + C = A + (B + C)
(A.B).C = A.(B.C)
Distributive
A.(B+C) = A.B + A.C
The Binary concept
1's and 0's
1 = ON
0 = OFF
Logic Gates
NOT
only has a single input and outputs the opposite of the input signal
OR
At LEAST one input must be 1 to receive an output
AND
All inputs must be 1 in order to receive an ouptut
Hardwired Logic vs. Programmed Logic
Programmed
Logic is controlled by a program/language
Can be easily changed in the programming
Hardwired
logic control functions
that are determined by the way devices are electrically interconnected
Strictly by how it is wired cannot be changed without changes to circuit
