    Measurements of the response of a nonlinear system to one or more inputs can be used to obtain an approximate mathematical statement of the way in which the response depends upon the input. Such a statement can be used to predict the response of the system to inputs other than those used in the measurements. A general approach is presented in which the response is approximated by a linear combinat... View full abstract»

    In the case of band-limited signals, the sampling theorem permits us to replace analytic operations with algebraic operations. We are then able to discuss problems of measurement of information, coding, and transmission over noisy channels in terms of discrete samples, rather than continuous time functions. The design of the optimum linear filter reduces from a very difficult analysis problem invo... View full abstract»

    This paper treats the analysis of nonlinear systems having more than a single degree of freedom. The method used is the Ritz or Ritz- Galerkin, which has been extensively applied to statical problems in elasticity and to eigenvalue problems of various types. Until very re- cently, however, it has rarely been applied to dynamical problems other than eigenvalue ones. As shown by some specific exampl... View full abstract»

    In many multi-loop nonlinear systems, it is possible to get from the original set of simultaneous differential equations a single differential equation of a higher order. The high order nonlinear differential equa- tion can be solved by an n -dimensional phase-space method, which is an extension of the phase-plane method. As an illustration, a three- loop system is analyzed. Numerical examples for... View full abstract»
