This heuristic technique works exploring the search space where we can also find circuits obtained through classical design techniques (
Karnaugh Map [15], Quine-McCluskey Algorithm and Boolean algebra), but also explore regions of space where there are unconventional circuits, which may be more suitable for some cases.
An excitation table for the D flip-flop is simplified and minimized by Karnaugh Map.
The code sequence is then simplified and minimized by Karnaugh Map.
It is clear that n-input Karnaugh map uses n variables to reserve memory storage and represents all the [2.sup.n] possible combinations.
The analogy between EKMR(3) and Karnaugh map with three- input is as follows[Fig.
The three most popular are minimisation techniques are: algebraic method,
Karnaugh map [5] and Quine-McCluskey procedure [3].
It's designed as a textbook, so college-level students and practicing engineers will find it most handy--but it covers all the basics, from Boolean algebra and logic gates to
Karnaugh maps. An accompanying cd-rom includes simulations and third-party software, making this highly recommended for any in-depth, practicing engineer or student.
Standard graphical design aids such as Karnaugh Maps [6] are widely used and tools suitable for computer implementation have evolved from the Quine--McCluskey method to freely available tools and commercial products.
6), the MGA, the NGA and two human designers (the first, using Karnaugh Maps and the second using the Quine-McCluskey Procedure) are shown in Table II.
