A Map Method for the Teaching of the Fundamental Concepts of Compound-Input Logic Circuits

One class of logic circuits has inputs that are functions of fundamental variables. Other inputs may include aspects of the fundamental variables themselves. A method for improving the understanding of these circuits, based on the Karnaugh map method, is presented here. In addition to providing a teaching tool, it has advantages when used as a design technique. It will show readily when there are no possible solutions, will test easily for constraints, and will present easily optimized solutions.
