  1. 1. Truck Connectivity Platform Using Software Defined Radios

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

    Författare :Srinath Vasan; [2019]
    Nyckelord :SEM; AM; FM; DAB; SDR; SEM; AM; FM; DAB; SDR;

    Sammanfattning : Hardware updates and feature updates of electronic equipment can take a long time for market implementations. Technology tends to become obsolete by the time the update is launched into the market. LÄS MER

  3. 2. Design, Implementation and Comparison of Demodulation Methods in AM and FM

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Gaojun Chen; Sen Lin; [2012]
    Nyckelord :Demodulation; Envelope; Coherent; Square-law; FM to AM; Zero-crossing; Quadrature.;

    Sammanfattning : Modulation and demodulation hold dominant positions in communication. Communication quality heavily relies on the performance of the detector. A simple and efficient detector can improve the communication quality and reduce the cost. LÄS MER

  4. 3. Hybrid Color Halftoning

    Master-uppsats, Institutionen för teknik och naturvetenskap

    Författare :Ahmed Tausif Aijazi; [2010]
    Nyckelord :Halftoning; Color; Hybrid; Flexography; Printing; image reproduction;

    Sammanfattning : Halftoning methods can be divided into two main categories, namely AM (Amplitude Modulated) and FM (Frequency Modulated). Some printing methods, such as Flexography, are not able to produce dots small enough to handle the highlights and the shadows of the original image by just using AM halftoning method. LÄS MER

  5. 4. Visuell utvärdering av frekvensmodulerat raster på obestruket papper.

    Kandidat-uppsats, Grafisk teknik

    Författare :Emilie Blomqvist; Veronica Cedergren; [2010]
    Nyckelord :Grafisk teknik; frekvensmodulerat raster; traditionellt raster; obestruket papper; låg total färgtäckning TIC ; densitet;

    Sammanfattning : This thesis investigated if a combination of increased under colour removal (decreasing the total ink limit), normal andincreased density and modern FM-screening could be used to provide a visually better print on uncoated and coated paperin comparison with AM-screening using the same conditions.Two different test groups (one with graphic background, the other with no graphic background) were asked to a visuallyassess the quality of the prints presented in a pair comparison using a reference image.

  7. 5. Does arbuscular mycorrhiza symbiosis increase the capacity or the efficiency of the photosynthetic apparatus in the model legume Medicago truncatula?

    Master-uppsats, Molekylär genetik

    Författare :Ateeq ur Rehman; [2010]
    Nyckelord :Medicago truncatula; Arbuscular mycorrhiza symbiosis; Photosynthesis; Chlorophyll fluorescence; Oxygen evolution; Lhcb1 and Lhcb2 proteins content; phosphor uptake; Reproductive fitness;

    Sammanfattning : The Arbuscular mycorrhiza (AM) is an endosymbiont of higher plant roots. Most land plants and cultivated crops are concerned to AM symbiosis. This endosymbiosis is based on the mutual exchange of nutrients between plant and fungus. Therefore, AM symbiosis leads to an increased demand for photosynthetic products. LÄS MER
