  1. 6. A speech therapy support tool based on spectral density adjustment

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Erik Stålberg; Artur Lidström; [2021]
    Nyckelord :speech therapy; spectral estimation; fundamental frequency estimation; FIR filter design; Mathematics and Statistics; Medicine and Health Sciences;

    Sammanfattning : The purpose of this work is to expand the toolbox of speech language pathologists and give them the ability to redesign a patient’s voice to a healthier sounding one, thereby giving the patient a target voice to strive towards. A modified voice is generated by applying a finite impulse response (FIR) filter, altering the spectrum of the patient’s voice. LÄS MER

  3. 7. Adder Minimization and Retiming in Parallel FIR-Filters : Targeting Power Consumption in ASICs

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Jens Månsson; [2021]
    Nyckelord :FIR-filter; retiming;

    Sammanfattning : Parallelized implementations of FIR-filters are often used to meet throughput and power requirements. The most common methods to optimize coefficient multiplication in FIR-filters are developed for single rate filters, thus the added redundancy of parallel implementations cannot be utilized in the optimization.

  4. 8. Design parameterizable filter using High Level Synthesis

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

    Författare :Troels Maehl Folke; Wenqian Ding; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As the ASIC designs continue to grow in complexity, traditional RTL level of abstraction is becoming a productivity bottleneck. The RTL design process requires extensive time and effort for verification of algorithmic correctness as well as correct timing and interface behavior. LÄS MER

  5. 9. Blind Channel Equalization for Shortwave Digital Radio Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tomas Busk; [2020]
    Nyckelord :Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Sammanfattning : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  7. 10. Independent Project Thesis in Electrical Engineering : Design and implementation of digital filters

    Kandidat-uppsats,

    Författare :Linus Ryttermalm; Gustav Vallinder; [2019]
    Nyckelord :digital filters;

    Sammanfattning : This thesis describes and discusses design and implementation of digital filters inembedded systems. Digital filters provide great flexibility where an interchangeablefilter is needed and real valued components are limited. Common sampling problemssuch as aliasing and reconstruction are discussed and solved using analog filters. LÄS MER
