|Introduction Boolean Algebra - Lesson 2|
You can use Boolean algebra as a shorthand notation for digital circuits.
Output of the first gate:
X3 = A + B
Output of the second gate:
X6 = X3 + C = A + B + C
The final output is:
X8 = X6 + D = A + B + C + D = X
HO: Find the Boolean equation for the following circuit.
X = (A + B) (C + D)
