The Karnaugh map (KM or K-map) is a method of simplifying Boolean algebra expressions. Maurice Karnaugh introduced it in as a refinement of Edward Veitch's Veitch chart, which actually was a rediscovery of Allan Marquand's logical diagram aka Marquand diagram but with a focus now set on its utility for switching circuits. Online Karnaugh Map solver that makes a kmap, shows you how to group the terms, shows the simplified Boolean equation, and draws the circuit for up to 8 variables. A Quine-McCluskey option is also available for up to 6 variables. E&CE Department of Electrical & Computer Engineering, University of Waterloo 70 of 92 Karnaugh Maps (K Maps) A Karnugh map is a graphical representation of a truth table The map contains one cell for each possible minterm adjacent cells differ in only one literal, i.e., x or x’ Two variables, F =f(x,y) Function is plotted by placing 1 in cells corresponding to mint-.

Previous GATE Questions on K-Map, SOP and POS expressions ( - Till Date) Using the K-map minimize the function in the sum of products form. Also, give the realization using only two input NAND gates. Answer: f = AD' + AC + B'C and lovemybrand.net NAND gates required = 6. EEE/ETE Digital Logic Design Topic 3: Gate-Level Minimization (K-Map) Fahimul Haque (FHE) Dept. of Electrical & Computer Engineering * Slides are used as an aiding tool to teach in the classroom. Not every information/details are mentioned on the slides that will be taught in the classes. Hence, you are expected to follow the given textbook(s) for your course. Shown below is a K-map for four variables. Note the following about the four variable Karnaugh Map. There are 16 cells in the map. Anytime you have N variables, you will have 2 N possible combinations, Either way will take the same number of gates, inputs, etc. And another observation. Online Karnaugh Map solver that makes a kmap, shows you how to group the terms, shows the simplified Boolean equation, and draws the circuit for up to 8 variables. A Quine-McCluskey option is also available for up to 6 variables. The outputs of a truth table correspond on a one-to-one basis to Karnaugh map entries. Starting at the top of the truth table, the A=0, B=0 inputs produce an output α. Note that this same output α is found in the Karnaugh map at the A=0, B=0 cell address, upper left corner of K-map where the A=0 row and B=0 column intersect. Larger 5 & 6-variable Karnaugh Maps Chapter 8 - Karnaugh Mapping. Larger Karnaugh maps reduce larger logic designs. How large is large enough? That depends on the number of inputs, fan-ins, to the logic circuit under consideration. One of the large programmable logic companies has an answer. 1 ea triple 3-input NAND gate AX’, ABY.
