1. Design av slutsteg med digital PWM-teknik för gitarr
Magister-uppsats, Institutionen för systemteknikSammanfattning : Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. LÄS MER
2. 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.
