Present work describes the integration issues of the reconstruction module for audio
applications into high fidelity audio amplifier based on a real model of consumer grade digital stereophonic audio distribution.
First chapter summarizes the work objectives, describes physical properties of sound
and gives a brief background overview of the related issues.
Second chapter describes addressed issues in detail, in particular the model of home and
car audio system, the target module application fields. Followed by the introduction of
expected problems and technological limitations, and a presentation of requirements and
boundary conditions based on a review of trends.
Third chapter presents the design and implementation of proposed solution with respect
to design guidelines consideration and information provided by manufacturers.
Fourth chapter summarizes designed circuit performance, which is evaluated through a
series of comprising parts measurements. Final evaluation confirms the feasibility of the
proposed design approach.
In conclusion, the results show that the integration of parts raises the design complexity
level caused by combining analogue and digital components. Improvements and future
module extensions, which include the use of fixed voltage regulators, multilayer PCB,
improved control of the circuit with microcontrollers, the use of wireless communication and many more are also presented.
