  1. 1. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

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

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  3. 2. Medical Signal Preparation and Proof of Concept for a Display and Diagnosis Application : Transmission, Display and QRS detection of an ECG Signal

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :David Fogelberg Skoglösa; [2021]
    Nyckelord :Signal display; Analog to digital conversion; QRS-detection; Application ECG-diagnosis; Real-time.;

    Sammanfattning : In many developing countries health care conditions are poor and there is a lack of healthcare professionals and diagnostics tools. Cheap and easy-to-use diagnostics tools have been developed to make practicing medicine easier under these conditions. LÄS MER

  4. 3. Ring amplifiers for high speed pipeline assisted SAR ADCs

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

    Författare :Johan Holmstedt; [2020]
    Nyckelord :ADC SAR RAMP ring amp residue amplifier PVT; Technology and Engineering;

    Sammanfattning : This thesis contains a review of published ring amplifier topologies. It is suggested to split the input stage of the ring amplifier into two. In this way, a robust ring amplifier can be designed without stacking the transistors in the second stage of the ring amplifier, boosting its speed properties. LÄS MER

  5. 4. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Pablo Martinez Cano; [2019]
    Nyckelord :LISA; PCB; temperature; passive; aluminum; aluminium;

    Sammanfattning : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

  7. 5. Design and Implementation of Sigma-Delta Converter : in Oversampling frequency

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Yaobin Pan; Xizhuo Li; [2016]
    Nyckelord :Sigma-Delta converters; Oversampling; Analog-Digital converters;

    Sammanfattning : Nowadays, Sigma-Delta analog-to-digital converters have been widely used in the technology of analog-to-digital conversion. It depends on the merits that the approach of Sigma-Delta has. The signal converted by oversampling is precise and well-suited in signal processing systems. LÄS MER
