Osaamistavoitteet
The solution of various mathematical problems becomes considerably easier, if the functions under study are replaced by their integral transforms. When a function is replaced by its integral transform, the function transforms, by means of integration, to a new function of a new variable. The most imnportant integral transforms are the Fourier transform, which is applied, in particular, in the analysis of vtyhe oscillatory phenomena, and the Laplace transform, which is used in the solution of differential equations. Closely related to the differential equations are the so-called difference equations, which have sequences as their solutions. The difference equations may be solved by means of the so-called z-transforms. In this course, which is heavily based on the complex analysis learned in the Advanced Analysis course, the student learns the basics of all these transforms and their application.
