A primer on Karnaugh maps
Simplification can actually reduce the number of logic gates you need. And Karnaugh maps are a good simplification tool.
Last time, I introduced the ideas behind symbolic logic, logic circuits, and so on. This month, I'll talk more about minimizing logic equations; but before we start, I'd lik... | {"url":"http://www.embedded.com/electronics-blogs/programmer-s-toolbox/4024897/A-primer-on-Karnaugh-maps","timestamp":"2014-04-21T02:14:05Z","content_type":null,"content_length":"84020","record_id":"<urn:uuid:1a35e0b0-bf0c-454f-8c22-41eeb204fcbc>","cc-path":"CC-MAIN-2014-15/segments/1397609539447.23/warc/CC-MAIN-201404... |
