  1. 1. IP block signalbehandling

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Holmlund Joakim; [2021]
    Nyckelord :CIC; Digitala filter; FIR; FPGA; IIR; Inbyggda system; IP block; Signalbehandling;

    Sammanfattning : The thesis aims to implement different digital filters such as finite impulse response (FIR), infinite impulse response (IIR) and cascade integrator comb (CIC) on the field-programmable gate array (FPGA) development board using hardware description language (VHDL). To this purpose, Intel’s systems integration tool Platform designer is used to convert the implementation to an IP core. LÄS MER

  2. 2. A study on the decimation stage of a Δ-Σ ADC with noise-shaping loop between the stages.

    Master-uppsats, Elektroniksystem

    Författare :JayaKrishna Gundala; [2011]
    Nyckelord :Oversampling ratio; Noise-shaping; Δ-Σ ADC; Filter Optimization; FIR filter; CIC filter; Decimation;

    Sammanfattning : The filter complexity in the multi-stage decimation system of a Δ-Σ ADC increases progressively as one moves to higher stages of decimation due to the fact that the input word length of the higher stages also increases progressively. The main motivation for this thesis comes from the idea of investigating a way, to reduce the input word length in the later filter stages of the decimation system which could reduce the filter complexity.

  3. 3. Design of a Digital Down Converter for LTE in an FPGA

    Kandidat-uppsats, Akademin för teknik och miljö

    Författare :Emil Krantz; [2010]
    Nyckelord :;

    Sammanfattning : In thesis a Digital Down Converter (DDC) for Long Term Evolution (LTE) signals is designed. The DDC shall be implemented in hardware in a Field Programmable Gate Array (FPGA). For an FPGA the desired operating speed is high. The purpose of this thesis is therefore to determine if it is possible to design such a system. LÄS MER

  4. 4. Power Efficient Digital Decimation Filters for Sigma-Delta ADCs

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Love Cederström; [2009]
    Nyckelord :Decimation Filter; Sigma-Delta; Low-Power; Low-Frequency; CIC;

    Sammanfattning : The development of integrated circuit technology seen in the last decades has enabled a large variety of battery operated equipment to emerge, such as smallsensors and medical implants. These applications often has low requirements on sampling frequency but require a very low power consumption to achieve a longbattery life. LÄS MER
