Colloquium "Digital Processing of High-Dynamic Analog Signals"

Abstract:

In recent years digital signal processing has become unavoidable in all areas of electrical engineering. However, the signals appearing in the real world are mostly analog. Their conversion into the digital domain is performed by analog to digital converters (ADCs). These components are built using mature and well established technology resulting in their high performances. However, in applications which deal with high dynamic range signals, ADCs are still bottlenecks of the overall design. In this lecture, such applications are briefly described. Then the influence of ADC's nonlinearity is analyzed and recognized as critical design parameter. Finally, the method for mitigation of undesired effects caused by nonlinearities is discussed.

Mladen Vučić was born in Karlovac, Croatia, in 1965. He received the Diploma Engineer, M.Sc., and Ph.D. degrees in electrical engineering from the University of Zagreb, Zagreb, Croatia, in 1989, 1993, and 1999, respectively. Since 1989, he has been with the Department of Electronic Systems and Information Processing of the Faculty of Electrical Engineering and Computing, University of Zagreb. Currently, he is a Professor of Electrical Engineering. Prof. Vučić was principal investigator of four scientific projects and one research project, all granted by the Ministry of science, education and sport of the Republic of Croatia. He was also a principal coordinator or collaborator on many research and development projects in cooperation with industry. He published more than 40 papers in journals and conference proceedings. His research interests include circuit theory, analog and digital signal processing, optimization theory and applications, and digital system design.
