Due to the need of increasing the efficiency of digital data processing and transmission systems, the requirements for ensuring a high level of their noise immunity are often increasing. The need for noise-immune processing and transmission of information usually arises when the data are quickly read from sensors, processed and transmitted through communication channels. In this case, it is desirable to use noise-immune codes, which simultaneously allow both processing of information and transmitting it through communication channels, as this allows to reduce the amount of equipment, make it more reliable and increase the speed of information processing and transmitting. In such a case, there is an end-to-end control of information with the same code. Among the noise-immune codes, there are codes that solve the posed problem of end-to-end control. Such codes are inseparable codes, and among them equilibrium, binomial and Fibonacci codes. The authors in this work conducted justification of such codes usage in noise-immune systems for processing and transmitting the information. The peculiarity of the indivisible code considered in this article is that they are minimal, which means that the counting and counters based on them will be simpler and more reliable. In addition, they more easily detect and partially correct single errors. Information from the counter can be sent directly without an encoder to the communication channel, where some occurring errors will be detected and, if necessary, corrected. The disadvantage of such coding will be the need to translate the indivisible information into binary code at the receiving end in some cases. However, this is not always required, since this information is often a control one and is displayed on the corresponding display devices.
