Abstract:

The realization of linear discrete systems, in an effective and efficient form, is the concern of this study. Emphasis is placed on problems of real-time implementation of such systems for uses including control of physical systems and on-line signal processing as well as system modeling. Recursive discrete systems are utilized, and methods are given for obtaining a set of equations for realizing, on the digital computer, an equivalent to a linear system. Results of particular note include 1 a study of methods for selecting the sample rate for a digital realization of an equivalent continuous system 2 a comparison of discrete and continuous convolution and the determination of weighting functions and 3 a study of the need for a data-reconstruction of hold circuit in the sampled-data realization of a continuous system. From these, the best form of the resultant difference equations for digital realization, in terms of accuracy, stability, and computer requirements, can be determined. Author
