  1. 1. Analyzing the efficacy of the FFT in Image Denoising and DigitalWatermarking

    University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Author : Emil Fagerström; [2023]
    Keywords : FFT; Image Denoising; Digital Watermarking;

    Abstract : The FFT has been a staple in the field of mathematics and computer science for almost 60 years. And yet, it still endures as an efficient algorithm in a multitude of fields. READ MORE

  3. 2. Audio Thermometer : Determining Water Temperature By Its Sound

    University essay from

    Author : Hannes Rohlin; Jesper Thulin; [2022]
    Keywords : Sound; Water; Temperature; Machine Learning; Thermometer; Audio; FFT; Ljudtermometer; Ljud; Vatten; Temperatur; Maskininlärning; Termometer; Ljud; FFT;

    Abstract : In this project, the temperature of water was to be determined by recording the sound made whilst being poured into a container. The goal was set to achieve an accuracy of at least 80% of measurements should be predicted within ±10°C and a negligible amount outside ±20°C. READ MORE

  4. 3. Using HLS for Acceleration of FPGA Development: A 3780-Point FFT Case Study

    University essay from Linköpings universitet/Datorteknik; Linköpings universitet/Tekniska fakulteten

    Author : Christoffer Hejdström; [2022]
    Keywords : 3780; hls; fpga;

    Abstract : Manually designing hardware for fpga implementations is time consuming. Onepossible way to accelerate the development of hardware is to use high level syn-thesis (hls) tools. Such tools synthesizes a high level model written in a languagesuch as c++ into hardware. READ MORE

  5. 4. 64-point FFT Instruction Implementation and Evaluation on a Microcode Programmable Processor

    University essay from Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

    Author : Yongjun Liu; Zejun Huang; [2022]
    Keywords : FFT; Instruction design;

    Abstract : Fast Fourier Transform is an efficient algorithm for computing the Discrete Fourier Transform (DFT) and one of the most important algorithms used in many digital signal processing applications over decades. This thesis presents an efficient implementation method of a 32-bit complex number 64-point FFT instruction on a micro-programmable processor. READ MORE

  6. 5. Fluid Surface Velocity Measurement Using Millimeter-Wave Radar Sensor

    University essay from Lunds universitet/Matematisk statistik

    Author : Gustav Broman; Leo Ghatnekar Nilsson; [2022]
    Keywords : Fluid flow surface measurement; velocity estimation; FFT; fast-time phase change; radar.; Mathematics and Statistics;

    Abstract : Contactless fluid surface velocity measurements with radar technology presents novel ways of determining fluid flow. The Acconeer A121 sensor is used, which is a pulsed coherent 60 GHz millimeter-wave radar, with high accuracy and low energy consumption. READ MORE
