USE OF STRUCTURAL RESERVES FOR INCREASING THE RELIABILITY OF AUTOMATIC DEVICES,
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 1/2. 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.
