In this post, we will see the book Random Processes In Electrical And Mechanical Systems by V. L. Lebedev.

About the book

This book deals with stationary and non-stationary random processes in linear systems and in inertialess nonlinear systems which have either one or several in­puts and outputs. The application of the mathematical methods expounded is illus­trated by many practical examples related to various physical and engineering pro­blems.

The book was translated from Russian by J. Flancreich and M. Segal  and was published in 1961 by The Israel Program for Scientific Translations.
