The development in Electronics increases the demand for good design methods and design tools in the field of electrical engeneering. To improve their design methods Ericsson Microwave Systems AB is interested in using computer tools to create a link between the specification and the implementation of a digital system in a FPGA. Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.

This is a report of our examination project in Electronics carried out for Bofors Test Center in Karlskoga. The task was to construct an electronic devise for starting up different kinds of measuring systems in exact time during test sequences. The modules that are used today are old and unreliable. Our goal was to construct a prototype, which later on is supposed to be developed into a useful system..

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power Electronics and a current measurement system for active magnetic bearings (AMB).

The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

Implementering av FIR filter kan göras på olika sätt. I detta examensarbete har två olika varianter beskrivits med hjälp av VHDL, syntetiserats, simulerats och sedan jämförts med avseende på effektförbrukning..

ABSTRACT  Title:                                       Artifacts as transformational leaders ? A case study at SIBA. Course:                                   Bachelor Dissertation - Leadership Authors:                                 Tobias Barin and Victor Eriksson Advisor:                                 Anders Billström Keywords:                             Artifacts, transformative leadership, organizational culture and leadership Problem formulation:          Which artifacts can be transformative leadership in the Electronics industry?  Purpose:                                Create an understanding of store managers and deputy store managers' perception of how artifacts can be expressed in the transformational leadership.                                                Creat an understanding of the importance of artifacts in leadership in the Electronics industry. Theoretical framework:       The study?s starting point for the theoretical framework has been Schein (2004) earlier theories of organizational culture, and Bass (1985) theories of transformational leadership. The link between organizational culture and transformational leadership is the basis for the chosen theories. Methodology:                        We conducted a qualitative method with a deductive approach for intent a solution for problem. Personal interviews were conducted with two store managers and two deputy store managers at SIBA. Conclusion:                           We have found that the artifacts: role-models, stories and rituals communicate the transformative leadership. Respondents have described how these artifacts conveys organizational culture but also the transformational leadership..

This report is about a thesis that is performed in and for SYSteam Engineering AB in Motala. The thesis work is divided into three parts, study of the market, programming and Electronics. The study part consists of examining and comparing different data acquisition systems for testing of different circuit boards, taking into account the modularity, real-time applications, mobility, environmental, interface hardware and software, to be able to define a general module-based data acquisition system in both hardware and software that enables for future developments.The programming part consists of getting started with Visual Studio, which integrates the Measurement Studio for C#. NET. Measurement Studio includes classes and user controls for testing and measuring and offers tools for acquisition, analysis and presentation of real world data.

When implementing syncronous filters with global clock nets, a substantial amount of energy is consumed in the clock net. Hence, it is interesting to reduce the size of the clock net, which in turn will reduce the total energy consumption. One way to acheive this, is to create a SIC (Structured Interfacing of Computational elements) since such a structure can be created without a global clock net. Our results show that a fifth order wavedigital filter with a sample rate of at least 10M samples/sec may be achieved.

DARC är ett sätt att sända digital information via FM-rundradionätet. Moduleringsmetoden för DARC är GMSK. Målsättningen var att jämföra kostnad/komplexitet och strömförbrukning för olika sätt att demodulera GMSK. Tre icke-koherenta demodulatorer och en koherent demodulator har jämförts. Man vill veta hur stor resursanvändningen var för olika FPGAer.

As requested by the company Husqvarna AB, we have developed a prototype of an electrical start device to a chainsaw. This was done through the development of new details in Catia, which has been integrated with existing details. Electrical components have been purchased by HAB Electronics. In parallel with the modeling calculations was done, which was the basis for determine dimensions and the choice of an electric motor and gears. Prototype 1 improved gradually and led to prototype number 2, which became the final result.

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..

Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..
