Application of statistical techniques to electron tubes for use in a 4,000-mile transmission system

OVER the past several years the subject of reliability of electronic equipment has received considerable attention. Much has been written on the need for reliable systems, and the mathematical probabilities of component performance have been explored. While there have been demonstrations of achievement, it is felt that additional material of this nature will be of interest. One of the chief factors in establishing a reliable system is to assure compatibility of the operating environment and the capabilities of the active electronic device. This can best be brought about by close cooperation between the equipment and component designers.
