  3. 7. RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem

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

    Författare :Kishore Khed; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

  4. 8. A Differential Measurement Probe with High Common Mode Rejection

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Björn Franzén; [2018]
    Nyckelord :Common mode rejection; Fiber-optic measurement probe; Current Sensing; High voltage measurements; Optical isolation; Technology and Engineering;

    Sammanfattning : Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering.

  5. 9. Highly linear attenuator and mixer for wide band TOR in CMOS

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

    Författare :Hind Abdalslam Abdallah Dafallah; [2016]
    Nyckelord :TOR; Attenuator; Mixer; Linearity; PA; Technology and Engineering;

    Sammanfattning : In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. LÄS MER

  7. 10. Customer Loyalty in an Internet Banking Context

    Magister-uppsats, Institutionen för ekonomi och företagande

    Författare :Erika Jansson; Maria Letmark; [2005]
    Nyckelord :företagsekonomi; bank;

    Sammanfattning : The importance of Internet in banking increases as more people use Internet as their main channel in contacts with their bank. This poses both possibilities and threats to the bank and having loyal customers become more important. LÄS MER
