  1. 6. Designing and Evaluating a Delta-Sigma DAC for Hi-Fi Audio : To be used in an FPGA implementation

    University essay from Linköpings universitet/Datorteknik

    Author : Gustav Malmström; [2023]
    Keywords : Delta-Sigma; DAC;

    Abstract : This thesis describes the design of a digital-to-analog converter using a DeltaSigma modulator. The converter’s purpose is to be used for Hi-Fi audio. The thesis is limited to the digital domain of the converter, which is the digital interpolation filter and digital Delta-Sigma modulator. READ MORE

  3. 7. Wave Propagation Experiment on FPGA with Miniaturized Payload for Sounding Rocket Application

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

    Author : Leonardo Filippeschi; [2022]
    Keywords : Wave propagation experiment; REXUS BEXUS; FPGA; IQ demodulation; ADC; VHDL;

    Abstract : This bachelor's thesis aims to implement a wave propagation experiment on Field-Programmable Gate Array to detect the signal strength at pre-defined frequencies for use in sounding rocket experiments. This includes the choice of suitable components such as analog to digital converters, filters, voltage regulators, and amplifiers. READ MORE

  4. 8. 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

  5. 9. Avoiding Frequency Cancellation Using Multiple Microphones in a Surveillance Camera

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Victoria Ringsmose; [2021]
    Keywords : Audio; analog electronics; acoustics; interferense; cancelled frequencies; surveillance; multiple microphones; frequency analysis; crossover filter; analog filter; Technology and Engineering;

    Abstract : In surveillance it is important that the recordings are accurate and in as high quality as possible. The surveillance surroundings and equipment can alter and change the audio and needs to be compensated for. This master thesis project investigates whether using multiple microphones could improve the audio quality. READ MORE

  6. 10. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE
