  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. Designing and Evaluating a Delta-Sigma DAC for Hi-Fi Audio : To be used in an FPGA implementation

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Gustav Malmström; [2023]
    Nyckelord :Delta-Sigma; DAC;

    Sammanfattning : This thesis describes the design of a digital-to-analog converter using a DeltaSigma modulator. The converter’s purpose is to be used for Hi-Fi audio. The thesis is limited to the digital domain of the converter, which is the digital interpolation filter and digital Delta-Sigma modulator. LÄS MER

  5. 4. Design of a 16 GSps RF Sampling Resistive DAC with on-chip Voltage Regulator

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Pontus Thomsson; Cyrus Seyed Aghamiri; [2021]
    Nyckelord :DAC; LDO; RDAC; 16GSps; 12-bit; Digital-to-Analog Converter; Low-Dropout Regulator;

    Sammanfattning : Wireless communication technologies continue to evolve to meet the demand for increased data throughput. To achieve higher data throughput one approach is to increase the bandwidth. One problem related to very large bandwidths is the implementation of digital-to-analog converters with sampling rates roughly in the 5 to 20 GHz range. LÄS MER

  7. 5. Linearization of Resistive Digital-to-Analog Converter for RF-Applications Using Compensator and Digital Predistortion

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Henrik Eklund; [2021]
    Nyckelord :DAC; RDAC; DPD; Linearization; Digital-to-Analog Converter; Resistive Digital-to-Analog Converter; Digital Predistortion;

    Sammanfattning : High-speed digital-to-analog converters are critical components in many radiofrequency (RF) applications. The resistive DAC (RDAC) architecture is suitable for high-speed implementation in extremely scaled digital circuit nodes. LÄS MER
