A new method of the reduction of over-Karnaugh map for N≥5 switching function is presented,which introduces the construction principle of over-Karnaugh map,general property,neighbouring difference criterion,the rapid construction of over-Karnaugh map,reading diagram rule,the cover of reducing dimension,and application example.

Absolute encoder based on Karnaugh map;

Simplied one-way Karnaugh map method for optimization of logic design;

The Karnaugh map applies in the logicalfunction transformation and in the MSI logic circuit design;

Here introduce the tradition method and exactitude fast conversion method by contrast, including logic truth table, logic functional formula and Karnaugh.

The Improvement and Application of the drawing method of Karnaugh diagram;

The Maximum Formula of Logic Function and Its Simplification of Karnaugh Diagram;

This paper brieny discusses the question-how to use the pointclass diagram of multiple dimension to simplify the logistic equation, The point-classdiagram of multiple dimensions is more audio-visual vivid and simple than the wenn diagram and karnaugh diagram in the course of count and it can also express the logisticrelations of more than four dimensions.
