初次登臺

Examples of Applications,apters, to familiarize the reader with these powerful tools. Now we should like to prove the interest these theoretical developments have for the study, the design, or the analysis of logical systems, electronic computers or logical machines which serve as tools.

Theoretical Study of the Real Functioning of Binary Switching Elements-Non-Binary Switching Elementhave to be considered in order to explain how a relay (for example) functions. The most important work done in this field is due to the Roumanian school under the direction of Moisil. We highly recommend the interested reader to refer to these works, cited in the bibliography, in order to have a more complete treatment.

Reduction of the Number of States in a Table,Suppose we wish to realize a ‘2 counter’, that is, a one input, X, one output, Z, sequential system such that the output Z takes the logical value 1 with each even order X pulse. If we apply the Gloushkov synthesis technique and consider that we deal with an asynchronous system, we have(letting. to avoid complicated formulas):

Mast-Cell

Assignment of the Internal States (Asynchronous Sequential Systems),In Chapters 6, 7, 8, the synthesis of a sequential machine was performed from imposed specifications and a simple form of representation (the most compact form possible) was obtained by reduction processes.

Assignment of Internal States (Synchronous Systems),We shall not restate all that was said at the beginning of the last chapter. It is sufficient to recall that assignment represents an important step in the realization of a sequential machine. However, it seems a good idea to insist on the fundamental difference between the problem for synchronous and asynchronous systems.
