Classical Representations

Abstract

To be able to work with concrete switching functions, a description of these functions is required. Of course, there is a very broad spectrum of possible description types. Basically, the representation has to describe the function adequately and thoroughly, i.e., it must be completely clear from the representation which switching function is considered. Besides this fundamental condition, which has always to be satisfied, a series of further properties are desirable. For example, the description of a function should
  • be rather short and efficient

  • support the evaluation and manipulation of the function

  • make particular properties of the function visible

  • suggest ideas for a technical realization

and much more.
