Abstract:

The paper discusses a finite automan with the state set presented in the form of a system consisting of a combinational logic circuit and memory elements. Random malfunctions of the following type may occur in the logic elements and memory elements an element that must issue 1 at the output issues O instead, and vice versa. The satisfaction of the following conditions is presumed the probability of the distortion of the input signal of any memory element is low the errors of various memory elements are independent and their probabilities p are the same for every element and do not vary in time and, further, p is greater than 12. To enhance the probability of correct transition, h additional memory elements are introduced into the automation and k of its states are encoded in the words of some code having the length n equals k plus h with k information symbols and h redundant symbols. All the binary sequences x of the length n that do not coincide with any of the code words are termed distorted states of the automation.
