  1. 1. Implementation of adaptive filtering algorithms for noise cancellation

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Tanja Lampl; [2020]
    Nyckelord :;

    Sammanfattning : This paper deals with the implementation and performance evaluation of adaptive filtering algorithms for noise cancellation without reference signal. Noise cancellation is a technique of estimating a desired signal from a noise-corrupted observation. LÄS MER

  3. 2. Measurement system for low frequency and low amplitude AC voltage of given frequency

    Magister-uppsats, Högskolan i Gävle/Elektronik

    Författare :Viktor Kaltenböck; [2019]
    Nyckelord :;

    Sammanfattning : This work is about digital signal processing methods to be used to determine information of low frequency low amplitude signals of known frequency. Different adaptive filter concepts such as Wiener filter, NLMS filter and lock-in are implemented and compared to each other. LÄS MER

  4. 3. Detection of Emergency Signal in Hearing Aids using Neural Networks

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Vamshi Krishna Lakum; Arshini Gubbala; [2014]
    Nyckelord : Microphone Array; Fractional Delay; Beam Former; Adaptive Algorithms; Neural Networks;

    Sammanfattning : ABSTRACT The detection of an emergency signal can be estimated by the cancellation of surrounding noise and achieving the desired signal in order to alert the automobilist. The aim of the thesis is to detect the emergency signal arriving nearer to the automobilist carrying hearing aids. LÄS MER

  5. 4. Subband Adaptive Filtering Technique employing APA For Stereo Echo Cancellation over Audio Signals

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :BHANUDURGA SRI SATYA SIMHA EDAMAKANTI; VISHNU CHAITANYA GUNDU; [2014]
    Nyckelord :Stereo Echo Cancellation; NLMS; RLS; MCHA; APA; Subband Adaptive Modeling.; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : The world today is relying on hands free devices and teleconferencing equipments but the major problem with the use of these systems is creation of acoustic echo at the time of conversation. The quality of information to be transmitted and received is degraded due to the echo. LÄS MER
