Prerekvizity

The knowledge of basic laws and quantities in electrical circuits is required as well as characteristics of electric circuit elements, circuit behaviour with inertia elements, circuit topologies with operational amplifiers and their characteristics, periodical and non-periodical signal spectrum, continuous- and discrete-time systems. The student who enrols the subject should be able to use instruments for measurement of electrical voltage, current, and resonant frequency, waveform generators and oscilloscopes.

Plánované vzdělávací činnosti a výukové metody

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
- Lectures provide the explanation of basic principles, subject methodology, examples of problems and their solutions.
- Laboratory exercises support practical acquiring of themes presented at lectures. Active participation of students is needed.
Participation at lectures is recommended. Participation at other ways of instruction is checked.

Způsob a kritéria hodnocení

Evaluation of study results follows Rules for Studies and Examinations of BUT and Dean's Regulation to the Rules for Studies and Examinations of BUT. Up to 20 points is given for test from theoretical knowledge in the laboratory exercises. Up to 20 points is given for correct results and elaboration of all laboratory exercises. The minimal scale of elaboration of particular laboratory exercises and completive questions are specified by a regulation issued by the guarantee of the course and updated for every academic year. Up to 60 points is given for the final written examination and it is necessary to get at least 15 points for its successful completion. The exam consists of 10 groups of questions in the field of acoustics and electroacoustics according to the subject syllabus and one question is selected from each group.
