  1. 11. Antenna as a sensor for sensing available LTE networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Barath Kumar Sathish Kumar; [2022]
    Keywords : Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Abstract : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. READ MORE

  3. 12. Design and Verification of An Energy-Efficient Edge-Pursuit Comparator

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Haiqin Xie; [2022]
    Keywords : analog to digital converter ADC ; SAR; comparator; edge-pursuit comparator EPC ; edge-pursuit comparator enhanced with capacitor EPCC ; energyefficient.; analog till digital omvandlare ADC ; SAR; komparator; edge-pursuit komparator EPC ; edge-pursuit komparator förbättrad med kondensator EPCC ; energieffektiv.;

    Abstract : With the rapid development of mobile communication, sensors, and biomedical in recent years, the demand for accurate data information, highquality audio and image has become much more significant, which requires a high-precision Analog to Digital Converter (ADC) to process weak analog signals. As one of the core modules of ADC, the comparator’s precision, speed, stability, and noise play a key role in the performance of the whole circuit. READ MORE

  4. 13. Comparing Analog and Digital Non-Linear Sonic Signatures : an Investigation on Creative Application and Subjective Perception using the Universal Audio 1176 FET Compressor

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Behzad Mehrnoosh; [2021]
    Keywords : compression; compressor; non-linear; distortion; sonic signature; analog; hardware; digital; software; emulation; modeling; 1176;

    Abstract : Historically, compression was primarily used as a preventative measure to reduce the risk of clipping or overloading equipment in the recording signal chain. Research on the topic has revealed that modern production applications more commonly include utilizing compression as a creative effect, to impart distortion, manipulate timbre, and modify transients, rather than to control the dynamic range of audio signals.

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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

  6. 15. All-digital FPGA receiver : on Intel Stratix 10 TX

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Kim Persson; [2021]
    Keywords : FPGA; VHDL; Transceivers; Digital communication; ADC; PWM; QAM;

    Abstract : Ordinary digital receivers use analog mixers and conventional analog-to-digital converters. Thisthesis explores the possibility to build a receiver using an Intel Stratix 10 TX FPGA to sample asignal directly at its RF frequency. READ MORE
