  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.

    Sammanfattning : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. LÄS MER

  5. 4. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

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

    Författare :Magnus Wasting; [2021]
    Nyckelord :Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Sammanfattning : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. LÄS MER

  7. 5. Current sensing in software for electronic fuse applications : Analysis of two different current measurement implementations

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

    Sammanfattning : Relays and fuses are used in a multitude of applications to deliver and control current to its consumers. To improve the controllability of both the fuse and relay function, they can be moved to software. This will not only increase the number of available features but can also give live feedback of the systems current state. LÄS MER
