Teaching (in Czech)

Research interests

Applications of mathematical and physical ideas in different fields of technical computations, especially in discrete signal processing, multidimensional signals and systems, fast signal processing algorithms and array signal processing. His current research interest is concentrated on the integral transform relationships between linear difference and differential equations. He has been cooperated in the field of fuzzy sets and logic during the years 1999-2000.
