Abstract :
The paper presents, first of all, a definition of failure logical functions and an extention of boolean functions by defined failure logical functions. Then, asymmetrically failure logical circuits having only "0" failure and only "1" failure feature are assumed as fail-safe logical circuits. An architecture of the fail-safe logical system, which consisted of said logical circuits is depicted. And then, a structural principle and the practical example of fault-tolerant logical systems composed of duplex fail-safe logical systems having detectable functions of fault systems with fail-safe features are specified.<>
