Subject aims expressed by acquired skills and competences

To acquaint oneself with signal analysis, signal transmission and with sensor and transmission techniques of signal acquiring. To apply the theoretical basis, including selected application possibilities of interpretation.

Teaching methods



The subject is drawn up as both theoretical and practical subject of basic technical Bachelor study. It is an introduction to the theory of analyses and transfer of signals, above all by linear transfer systems. It is connected with respective parts of mathematics - theory of probability and statistics. It includes techniques of signal obtaining and a theoretical base for applications in practice.
