Mode of study

Not applicable.

Entry knowledge

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

Rules for evaluation and completion of the course

Evaluation of study results follows the Rules for Studies and Examinations of BUT and the Dean's Regulation complementing the Rules for Studies and Examinations of BUT. Up to 10 points are awarded for tests in theoretical knowledge in laboratory exercises. Up to 24 points are awarded for correct results and elaboration of all laboratory exercises and 6 points for submitting of project in software DAW. The minimal scope of the elaboration of particular laboratory exercises and complementary questions are specified by a regulation issued by the guarantor of the course and updated for every academic year. Up to 40 points are given for the final written examination and it is necessary to get at least 15 points for its successful completion. Up to 20 points are awarded for the final oral examination which consists of 10 groups of questions according to the course syllabus.
It is obligatory to work through all laboratory exercises in regular or alternative terms to complete the course. Other forms of checked instruction are specified by a regulation issued by the guarantor of the course and updated for every academic year.


The aim of the course is to make students familiar with the operation principle and use of analog and digital audio equipment, computer digital audio workstations and their installation in sound studios.
After course completion, students are to:
- describe the structure of the mixing console, explain its operation and use it for recording or sound reinforcement,
- explain the principles of measurement of level and other parameters of analog and digital audio signals,
- describe the structure and operation principle of the basic types of audio effects, describe the type of transformation which occurs in them, and use them for audio processing,
- explain the principle of digital audio signal processing and transmission,
- explain the principle and structure of digital audio signal hard disc recording (HDR),
- describe the structure of various types of audio interfaces and structure of digital audio workstations (DAW),
- describe the structure of the MIDI protocol, enumerate the messages it uses, and use them for controlling studio equipment,
- describe the types of synchronization signal, choose the proper type of synchronization for a given system,
- describe the structure of the DMX512 protocol and use it for controlling light and stage equipment.
