Sebesta, V.
Variables and functions for expressing quality of the prediction of the chaotic signal can serve as tools for simplified but useful description of the chaotic signal. In this paper, the known generation mechanism of chaos is used as a predictor but using the perturbed signal as an input. Prediction performance of the predictor is compared with the estimate of the predictability based on a mutual information between known quantities and a predicted value. mentioned two methods of investigation have different requirements for a priori knowledge of chaos. Certain constraints are given in consequence of an imperfection of numerical calculations and computer simulations.

Vrba, K.; Dostal, T.; Cajka, J.
Four types of second-generation current conveyors are shown. The realisation of the above conveyors using differential voltage current conveyors (VDCC) is presented. Two examples illustrate the building of adjoint networks containing second-generation current conveyors.

Chromy, I.
This paper treats of compression of digital video signals and the main aim is to probe the possibility of using several discrete transforms besides well-known discrete cosine transform (DCT). Mathematical description of these transforms is presented in the article. DCT and other orthogonal transforms are described here. Matrix notation of computation of two-dimensional transform is also presented. The comparison of the results obtained by application of the transforms on pictures is introduced.
