  1. 1. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures

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

    Author : Eduardo Salvador Lopez; [2023]
    Keywords : Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

    Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

  3. 2. Color Emotions without Blue Light : Effect of a Blue Light Filter on the Emotional Perception of Colors

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

    Author : Maximilian Leefer van Leeuwen; [2023]
    Keywords : Emotional Response; Blue Light; Blue Light Filter; Color Constancy; Color Perception; Color Emotion;

    Abstract : Blue light filters have become commonplace in modern technology. While there has been a substantial amount of research into their effects on sleep, there has been little into the effect on the media perceived through them. READ MORE

  4. 3. Development of an embedded system platform for signal analysis and processing

    University essay from Uppsala universitet/Signaler och system

    Author : Philip Lind; [2023]
    Keywords : Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

    Abstract : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). READ MORE

  5. 4. Circuit design and hardware implementation of an analog synthesizer

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Olle Murhed; [2023]
    Keywords : synthesizer; analogue; circuit design; sound; sound synthesis; oscillator; VCO; filter; amplifier; sequencer; control voltage; breadboard;

    Abstract : Since the heyday of analogue synthesizers in the 70's, they have largely been replaced by digital hardware and software synthesizers. However, in recent years, there has been a revival in analogue designs, possibly due to its ``warmer" sound. READ MORE

  6. 5. 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
