  1. 1. Preamplifier Design for Active Electrodes in Single-Channel EEG Applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Thorir Marwan Abed; [2018]
    Nyckelord :Electroencephalography EEG ; single-channel; active electrode; current feedback instrumentation amplifier CFIA ; DC servo loop DSL ; portability.; Elektroencefalografi EEG ; singelkanal; aktiv elektrod; strömåterkoppling instrumentförstärkare; DC servo loop DSL ; bärbarhet.;

    Sammanfattning : The implementation of portable electroencephalography (EEG) systems has been known to be complex. During ambulation, the integrity of recorded EEG signals is often impaired by motion artifacts and the time and effort required to set up the system is excessive. LÄS MER

  2. 2. Model based pulse shaping for detection of gamma rays

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Fredrik Ödmark; [2017]
    Nyckelord :pulse shaping; FWHM; CR-RC; electric noise model; analyse drill samples; gamma ray detector; matched filter; custom filter; clustering;

    Sammanfattning : To analyse drill samples in a mine, a scanner that uses a gamma ray detector can be used. The scanner can analyse the drill sample to quickly see the elements present in the sample without destroying it. LÄS MER

  3. 3. Extraction of energy and time from pile-up pulses with fast sampling ADC analysis techniques

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Anton Roth; [2016]
    Nyckelord :moving window deconvolution; alpha-decay; short-lived nuclei; digital pulse processing; Superheavy elements; decay paths; Physics and Astronomy;

    Sammanfattning : Debates of whether Z=114 and N=184 are the next magic numbers in nuclear physics have existed since the earliest predictions made in the 1960s. Until these days they have not been firmly established. LÄS MER

  4. 4. Implementation of a 200 MSps 12-bit SAR ADC

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

    Författare :Victor Gylling; Robert Olsson; [2015]
    Nyckelord :SAR; ADC; MCS; converter; circuit design; capacitor; Technology and Engineering;

    Sammanfattning : Analog-to-digital converters (ADCs) with high conversion frequency, often based on pipelined architectures, are used for measuring instruments, wireless communication and video applications. Successive approximation register (SAR) converters offer a compact and power efficient alternative but the conversion speed is typically designed for lower frequencies. LÄS MER

  5. 5. An Input Amplifier for Body-Channel Communication

    Master-uppsats, Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan

    Författare :Md Hasan Maruf; [2013]
    Nyckelord :Body-Channel Communication; Analog Front End; Capacitive Communication; Preamplifier; Schmitt Trigger; Body Area Network;

    Sammanfattning : Body-channel communication (BCC) is based on the principle of electrical field data transmission attributable to capacitive coupling through the human body. It is gaining importance now a day in the scenario of human centric communication because it truly offers a natural means of interaction with the human body. LÄS MER
