RANDOMIZATION OF SYMBOL REPETITION OF PUNCH CARDS WITH SUPERIMPOSED CODING IN INFORMATION-SEARCH SYSTEMS

Abstract

The article shows the effect of the irregularity of using separate symbols on search noise on punch cards with superimposed symbol coding in information-search system (IPS). A binomial law of random value distribution of repetition of each symbol is established and analyzed. A method of determining the maximum value of symbol repetition is proposed and an example of calculating this value for an experimental IPS is given.
