  1. 1. Design of a Differential Cross-Coupled Power LC Oscillator with ASK Modulation

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Sanjay Sarker; [2023]
    Nyckelord :Cross-coupled LC Oscillator; Amplitude Shift Keying ASK Modulator; Spiral Inductor; MIM Capacitor; Current Mirror Switching;

    Sammanfattning : Rapid growth in the field of communications industry has led to newer opportunities and challenges in the design of CMOS based monolithic integrated circuits. ASK modulators are a class of digital modulators which are known for their relative simplicity of implementation for low cost applications in the industrial and biomedical domains. LÄS MER

  3. 2. Frequency Tracking Using Digital Cavities

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

    Författare :Fredrik Zetterblom; [2017]
    Nyckelord :Digital cavities; Frequency Tracking; Technology and Engineering;

    Sammanfattning : Digital cavities are efficient algorithms for comb filters with very low computational costs. They have been used to precisely measure the amplitude and phase of high frequency signals (few giga samples per second) from data acquired by high speed digitizers 80 GSps. LÄS MER

  4. 3. QAM and PSK Modulation Schemes under Impulsive Noise

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Ezequiel Pérez Rodenas; [2012]
    Nyckelord :Impulsive noise; QAM; PSK; modulation; BER; APD;

    Sammanfattning :    Nowadays most of the communications systems are designed considering only to work under AWGN (Additive White Gaussian Noise). But the implementation of wireless systems in industrial facilities brings different kind of interference from machines or any other kind of electronic devices. LÄS MER

  5. 4. Simulation of Traveling Wave Electroabsorption Modulators for Phase Modulation

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Prasanna Ramaswamy; [2012]
    Nyckelord :;

    Sammanfattning : Electro-Absorption Modulators (EAMs) have been instrumental in achieving ultrafast modulation speeds of over 100 Gb/s, and in particular, segmented Travelling-Wave (TWEAMs) designs offer excellent compatibility with standardmicrowave technology due to their characteristic impedance being closer to 50. The TWEAM device fabricated as part of the European Project HECTO, has been succesful is field trials at 112 Gb/s using On-Off Keying (OOK). LÄS MER

  7. 5. Modeling Basic Physical Links in Acumen

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Muzeyen Hassen Esmael; [2012]
    Nyckelord :Acumen; Modulation and Demodulation; Simulation; RC Lowpass filter;

    Sammanfattning : Simulation is the process of computing a behavior determined by a given model of a system of interest.  Modeling is the process of creating a model that formally describes a given class of system.  Modeling and simulation can be used to quickly and cheaply study and understand new technologies.
