  1. 1. Image Reconstruction Techniques using Kaiser Window in 2D CT Imaging

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Md Monowarul Islam; Muftadi Ullah Arpon; [2020]
    Keywords : CT Imaging; Parallel-Beam Projection; 2D FFT; Radon Transform; Filters; Window Functions; Kaiser window; Inverse Fourier Transform; FBP.;

    Abstract : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. READ MORE

  3. 2. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Ahnesjö; [2020]
    Keywords : Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

    Abstract : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

  4. 3. Option Pricing using the Fast Fourier Transform Method

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

    Author : Abaynesh Berta; [2020]
    Keywords : Black-Scholes-Merton model; Characteristic function; Fast Fourier transform; Fourier Inverse Fourier transform; Option pricing;

    Abstract : The fast Fourier transform (FFT), even though it has been widely applicable in Physics and Engineering, it has become attractive in Finance as well for it’s enhancement of computational speed. Carr and Madan succeeded in implementing the FFT for pricing of an option. READ MORE

  5. 4. FFT Implemention on FPGA for 5G Networks

    University essay from Linköpings universitet/Datorteknik

    Author : Vlad Valentin Vasilica; [2019]
    Keywords : FFT; OFDMA; Physical design; FPGA; 5G; VHDL; CP-OFDMA; Radix-2; 2048-Point;

    Abstract : The main goal of this thesis will be the design and implementation of a 2048-point FFT on an FPGA through the use of VHDL code.The FFT will use a butterfly Radix-2 architecture with focus on the comparison of the parameters between the system with different Worlengths, Coefficient Wordlengths and Symbol Error rates as well as different modulation types, comparing 64QAM and 256QAM for the 5Gsystem.

  6. 5. Development of real time audio equalizer application using MATLAB App Designer

    University essay from Uppsala universitet/Signaler och System

    Author : Johannes Langelaar; Adam Strömme Mattsson; Filip Natvig; [2019]
    Keywords : Equalizer; Graphic equalizer; DSP; Digital signal processing; Audio processing; MATLAB; MATLAB App Designer; parallell filter;

    Abstract : This paper outlines the design of a high-precision graphic audio equalizer with digital filters in parallel, along with its implementation in MATLAB App Designer. The equalizer is comprised of 31 bands separated with a one-third octave frequency ratio, and its frequency response is controlled by 63 filters. READ MORE
