Transform the equations into logic gates. The Karnaugh map is a huge time saver as it removes the need to compute the Boolean expressions by hand. Minimal Product of Sum form can be achieved using Boolean algebraic theorems like in the non-canonical example given above. Solution: The Karnaugh map that represents this function is shown in Figure 4. Simplifying statements in Boolean algebra using De Morgan's laws. The material is brought to life through several applications including the mathematics of screen and printer displays. It is geared for those involved in engineering fields, more precisely digital and formal logic scholars and academics, digital devices constructors or anybody involved with logical expressions. I got AC' + CD + A'B'D. With the Karnaugh map Boolean expressions having up to four and even six variables can be simplified. to Computer Architecture University of Pittsburgh. For computer and electrical engineers among others, Karnaugh maps are a good way of simplifying Boolean expressions. The Karnaugh map provides a systematic method for simplifying Boolean expressions and, if properly used, will produce the simplest SOP or POS expression possible. Let's try another 3 variable map. No of vars can be controlled by the up/dn switch box. A set is a collection of objects out of a universe as shown below.
