Course detail

Design of Audio Electronic Devices

FEKT-BPC-NKZTAcad. year: 2020/2021

The basic principles of design and construction of low-frequency equipment are explained in a broader context. The course covers circuit principles, design methods, computer modeling, and practical design principles of various audio equipment such as mixers, sound effects, dynamic adjustment circuits, amplifiers, etc.

Learning outcomes of the course unit

The student of the course Design and construction of audio technology will understand the broader issue of external design and construction of equipment for audio equipment. Active knowledge of the design and construction of audio technology is a prerequisite for the effective use and real possibilities of these devices. Student will be able to understand the essential parts of the device, its design and diagnosis. Students gain a wider context, especially in the following areas:
- Basic principles of low-frequency devices and electronic circuits, electronic components for the implementation of audio circuits.
- Mixers, analysis of individual parts, tube amplifiers, echo, effect amplifiers, line amplifiers, pre-amplifiers, their practically verified topologies.
- Noise cancellers, Dolby systems, circuits for adjusting the dynamics of audio signals.
- Active and passive frequency crossovers.
- Pickups for musical instruments, instrument amplifiers, loudspeakers


Students should have basic knowledge of mathematics and electrical engineering, which gets in the mandatory subjects in the previous study. Their graduating is not a prerequisite for registration of this subject.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

0-30 points - laboratories
0-70 points – written exam, compulsory part of the completion of the course
Exam is focused to verify the orientation of the basic problems facing the design and construction of audio technology, the characterization of systems analysis and synthesis of simple audio systems.

Course curriculum

1. Basic principles of low-frequency devices
2. Electronic components for the implementation of audio circuits
3. Basic of electronic circuits for low-frequency technology
4. Mixers, analysis of individual parts
5. Tube amplifiers
6. Echos, effect amplifiers
7. Circuits for adjusting the dynamics of audio signals
8. Noise cancellers, Dolby systems
9. Pre-amplifiers
10. Active and passive frequency crossovers
11. Guitar (instrument) amplifiers, guitar loudspeakers
