The objective of this book is to provide a comprehensive background on nonlinear noise problems for practical applications in communication and control systems. The subject of nonlinear transformations of random processes can be studied either from the point of view of pure mathematics to gain appreciation of general theoretic principles or it can be studied from the point of view of applied problems motivated by models and requirements of physical systems. A mixture of these approaches was chosen for the exposition.
