In trying to design or adjust a dynamic system for optimum performance, the engineer is helped by a knowledge of theoretical limits on the capabilities of the system. Examples of such limits are the gain-bandwidth product of amplifier design and the coding theorem of information theory.

There are a number of new and powerful techniques rapidly being developed for the analysis and synthesis of feedback control systems. Four of these techniques are illustrated by some of the papers in this issue. One of the most fruitful of these is in the field of statistics, and in particular its application to nonlinear systems. R. C. Booton presents a paper which derives the cross-power density spectrum for a component with saturation or clipping. From this cross-power operator one can determine the quantity of output signal which is correlated with the input, the amount of harmonic distortion power present in the output, and an equivalent "gain" term satisfactory for use in testing for the build-up of periodic oscillations.

R. Booton
The describing-function method for the analysis of nonlinear systems with sinusoidal inputs is interpreted as a mean-square quasi-linearization technique and is generalized to apply to random signals. An amplitude-sensitive (or zero-memory) nonlinearity is interpreted as being approximately equivalent to a linear frequency-insensitive device, and a formula is derived for its equivalent gain. A simple rate-limited control system with a Gaussian input is analyzed as a specific application. Approximation of a general nonlinear element (containing memory) is considered next, and a relation between equivalent-system impulse response and the response of the actual nonlinearity is derived.
