Bio: Dr. Zsolt Kollár is currently a Fulbright scholar in electrical engineering at Kennesaw State University (KSU). He is also an associate professor at the Budapest University of Technology and Economics (BME) where he serves as the head of the MATLAB Laboratory. Previously he was a visiting researcher at Karlsruhe Institute of Technology. He is responsible for the maintenance and development of the Fdident (Frequency Domain Identification Toolbox) MATLAB Toolbox. His research interests include digital signal processing, system identification, quantization effects, and wireless communications.

Abstract: Quantization is the process of approximating a continuous signal through a set of discrete values. While physical quantities are precise, when digitized and inserted into a computer or a digital system, they are rounded to the nearest representative value. This process introduces quantization error, i.e., noise. This talk will introduce how to deal with digital systems where quantization is applied using statistical description of the process. Furthermore, fixed- and floating-point quantization will be also addressed. Finally, some examples will be shown where quantization play an important role.
