M. Lares, Karel Zaplatílek · Brno University of Technology Digital Library (Brno University of Technology) · 2001
In the article, we describe principles of numerical algorithms bymeans of which coefficients of continuous-time and discrete-timefrequency filters are possible to transform each other for several s-ztrans-formations. The basis of algorithms is so-called Pascal matrixfor calculation of which an original procedure is used. We discussproblems of numerical conditionality of Pascal matrix and possibilityof its practical usage. Illustrative examples of numerical calculationsprogrammed in Matlab 5.1 are the constituent part of the article.
