The transform has many applications in science and engineering because it is a tool for solving differential equations. In particular, it transforms differential equations into algebraic equations and convolution into multiplication. The Laplace transform is named after mathematician and astronomer Pierre-Simon Laplace , who used a similar transform in his work on probability theory.

The problem of stability of linear discrete systems and the root dis- tribution within the unit circle are discussed in detail in Chapter 3. This stability discussion is not yet available in any other text; it also represents some of my original work that is available only in papers. Thus the contents of this chapter could be very useful to applied mathematicians as well as to engineers and systems theorists.

Further development of the z-transform theory is considered in Chapter 4, with the derivation of the convolution of the z-transform and the modified z-transform. The application of the convolution theorem. The application of the convolution z-transform to the solution of certain types of nonlinear discrete systems or nonlinear difference equa- tions is emphasized in Chapter 5. Examples of the application of this method are also described. The stability study of limit cycles and their identification is also included.

The use of the z-transform method and its modification as applied to the approximate solution of differential equations or continuous systems is examined in Chapter 7.

The methods developed are well suited for digital computer analysis. Finally, in Chapter 8 are found various examples of areas in discrete system theory.

These areas include nonlinear sampled-data feedback system, discrete antenna array theory, information and filtering theory, economic systems, sequential circuits. The main emphasis is the application of the z-transform theory.

Extensive tables of z-transform, modified z-transforms. Further- more, there are many problems that illustrate further the application of the z-transform theory and indicate the method of the proofs of cert:lin theorems omitted from the text.

Kaplan have led to much improvement in the mathematics and they are greatly appreciated.

Since the major part of this material grew both from my research activities and those of my students, I would like to thank the Air Force Office of Scientific Research for their generous support and interest in our group at the University of California.

The patience and efforts of Mrs. Gilmore in typing this manuscript are gratefully appreciated and acknowledged.

This method will be extensively developed in this and other chapters with its modifications, extensions, and applications. Definition Let T be a fixed pOSitive number it could be taken as unity.

The Laplace transform is an extremely versatile technique for solving differential equations, both ordinary and partial. It can also be used to solve difference equations.

Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It only takes a minute to sign up. I've also seen generating functions as a similar way to transform a recurrence relation into an algebraic problem by diagonalizing the shift operator. The laplace transform of a convolution is a product of the laplace transforms for each function and similarly the generating function of a convolution is a product of generating function.
