Tutor:

Libor Husník

Supervisor:

Department of Radioelectronics

Synopsis:

The course is aimed at selected parts of electroacoustics and related fields with the emphasis on the theoretical aspect.

The main interest lies in electroacoustic transducers and their parts. Their description will include non-linear mode. The

part on measurement will include mainly calibration methods and their usage in cases close to topics of theses of

doctoral students.
