   Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

4. 3. 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

5. 4. SIGNALBEHANDLING MED AVANCERAD BLUETOOTH-TEKNIK OCH OPTIMERADE OPERATIVSYSTEM : Optimera audiosystemet i ett avancerat inbyggt system med en fler-trådad programvara och synkroniserings mekanism

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

   Författare :Omar Ibrahim; [2023]
   Nyckelord :BM83 bluetooth; audio subsystem; Inter-IC sound; Digital Signal Processor; Operative System; DSP platform tests.;

   Sammanfattning : This study is about replacing an old bluetooth module with a new variant, namely the BM83 which is an integrated circuit that contains an internal DSP circuit, profiles and important functions such as noise reduction, acoustic echo removal and EQ filtering. The purpose of this study is to replace the old module with the BM83, as well as explore the internal DSP circuit in the BM83. LÄS MER

7. 5. High Level Synthesis for ASIC and FPGA

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

   Författare :Malin Heyden; [2023]
   Nyckelord :HLS; high level synthesis; asic; fpga; catapult; filter; sfir; Technology and Engineering;

   Sammanfattning : This thesis aims to evaluate the performance of Siemens’ High Level Synthesis (HLS) tool Catapult. HLS can be considered the next step up in abstraction level from writing traditional Register Transfer Level (RTL) code which is time consuming and error prone. LÄS MER
