1. 1. Audibility & Preference of DA Overload Associated with True Peak : Investigation of claims made against overload prevention

   Kandidat-uppsats, Luleå tekniska universitet/Musik, medier och teater

   Författare :Mattias Strand; [2023]
   Nyckelord :true peak; mastering; inter-sample; intersample; peaks; peaking; overload; digital to analog; da; loudness; clipping; truncation; square wave;

   Sammanfattning : The conversion of audio from the digital to analog domain has the potential to result in distortion due to converter overload. This occurs because some peaks in the signal cannot be defined digitally and only become problematic during the conversion into the analog domain, exceeding the level that can be represented by the converter, causing it to overload.

3. 2. Development of an embedded system platform for signal analysis and processing

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Philip Lind; [2023]
   Nyckelord :Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

   Sammanfattning : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). LÄS MER

4. 3. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

   Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Eriksson Janze Oscar; [2023]
   Nyckelord :DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

   Sammanfattning : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. LÄS MER

5. 4. Design of a 13-Bit SAR ADC with kT/C noise cancellation technique

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Shashank Keerthy Kumar; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : One of the main limitations of a Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) is the large input capacitance needed to achieve the desired performance. This large input capacitance increases the total area of the ADC and it imposes the use of a powerful buffer to drive it. LÄS MER

7. 5. Implementation av mikrokontroller på en analog DC/DC-omvandlare : Konstruktion, programmering och testning som möjliggör digital funktionalitet på en analog omvandlare

   Kandidat-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Samuel Johansson; Skyler Ålund; [2023]
   Nyckelord :;

   Sammanfattning : The purpose of this project was to explore the possibility of using a general microcontroller for measuring and controlling a DC/DC-converter. The method for this implementation was to study the DC/DC-converter PKB4111D, planning the prototype board and constructing the board. LÄS MER
