The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on …
The goal of this work is to summarize the calculations for scaling and noise of twoportadaptor. Two different methods has been described and used for the final results.
implementering mot integrerade analoga kretsar
Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not …
The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical …
Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be …
The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage …
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 …
A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader …
This thesis is the result of the author’s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart …
This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one …
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape …
… som kan användas i kursen ”Design av mobila autonoma robotar” för studenter på Elektronikdesign vid Campus Norrköping. Arbetet har utgått från en modell som visar på robotens tänkta utseende. Utifrån ett antal kriterier har val av batterier, motorer och styrelektronik gjorts …
Detta examensarbete har utförts på uppdrag av Amersham Biosciences i Uppsala och undersöker hur ett specifikt instrument för proteinseparation skall kunna styras och övervakas över Internet. I arbetets inledning har en noggrann utredning av befintlig teknik utförts och utifrån …
<br /> en fallstudie på Saab Bofors Dynamics AB<br />
… en intervjubaserad fallstudie med respondenter från teknikområde Mekanik och Elektronik. Genom intervjuerna identifieras faktorer som bevarar och utvecklar teknologi. Många av faktorerna ger upphov till kunskapsöverföringar om teknologi, som identifieras både innanför och …
att till en spårningssändare formge en estetiskt tilltalande och tät IP67-kapsling för befintlig elektronik
… för arbetsvetenskap vid Luleå tekniska universitet. Uppdragsgivare var elektronikföretaget Followit AB i Skellefteå, som är ett modernt teknikbolag och arbetar med positioneringstjänster, mobil datakommunikation och datapresentation genom geografiska informationssystem …
