Design of Audio Electronic Devices
FEKT-BPC-NKZTAcad. year: 2019/2020
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.
Language of instruction
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 12. Pickups for electric and electroacoustic musical instruments 13. Proven connections of amplifiers and effects
The aim of the course is to deepen the existing and to acquire the new theoretical and practical knowledge in the field of the design and construction of low-frequency devices. Students will get acquainted with circuit principles and design solutions of sound and music electronics, will try their computer simulation, practical design, and measurement. The knowledge gained in courses focusing on general electronic circuits and on musical and acoustic technology is connected.
Specification of controlled education, way of implementation and compensation for absences
The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
