1. Simulation and Construction of a Half-Bridge Class D Audio Amplifier
Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : Usage of class D audio amplifiers has become increasingly widespread in recent years, mainly due to their high efficiency, which can reach almost 100 %. Class D amplifiers can also be compact, making them suitable for mobile applications. In contrast, the most efficient conventional amplifiers such as class B can reach a maximum efficiency of 78.

2. Implementation of a Function Generator
Kandidat-uppsats, Avdelningen för elektronik, matematik och naturvetenskapSammanfattning : Function generator has been widely used in each electronics fields recent years. In this thesis, the authors will introduce some basic structure and working principles of a function generator, moreover a function generator which can create three kinds of wave: sine wave, square wave and triangle wave has been implemented.

3. PWM Effekt Audioförstärkare
Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknikSammanfattning : The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal.
