The classical filtering and prediction problem is re-examined using the Bode- Shannon representation of random processes and the “state transition” method of analysis of dynamic systems. New results are: (1) The formulation and methods of solution of the problem apply without modifica- ...

The discussion is largely self-contained and proceeds from first principles; basic concepts of the theory of random processes are reviewed in the Appendix. Present methods for solving the Wiener problem are subject to a number of limitations which seriously curtail their practical class of theoretical...
In this way, basic facts of Hopf equation (which applies also to nonstationary problems the Wiener theory are quickly obtained; the scope of the results whereas the preceding methods in general don’t), has been and the fundamental assumptions appear clearly. It is seen that all pioneered by...
is prompted to quote Wiener's characterization of his relations with Birkhoff, presumably from one of Wiener's autobiographical works of a very much later date. I could indulge in a little speculation as to what was going on then and in Ms. Raid's conversations with Courant about the matter...
Reference [23] proposed an improved adaptive algorithm for LMS to perform adaptive filtering and noise reduction processing on fault signals to improve the SNR of the fault signals. To sum up, the existing traditional noise reduction methods have disadvantages such as mode aliasing, end effect, ...
In systems theory, we designate, by system, an entity that performs a given task. Its nature can be diverse—a machine or a company, a biological structure or a computer program, a circuit (of any fluid) or a communication system, etc. A system can, also, be a combination of these ...

Some nonlinear systems possess innate capabilities of enhancing weak signal transmissions through a unique process called Stochastic Resonance (SR). However, existing SR mechanism suffers limited signal enhancement from inappropriate entraining signals.
