Streszczenie:

Modern and future communication and radar systems require highly reconfigurable RF front-ends to realize the vision of Software-Defined Radio (SDR), where a single digitally-enabled radio is able to cover multiple bands and multiple operating standards. However, in the increasingly hostile RF environment, filtering becomes a bottleneck for SDRs as the traditional off-chip filters are fixed frequency and bulky. Therefore, tunable filtering is a critical building block for the reconfigurable RF front-ends and on-chip implementations are needed to meet size and weight constraints. On-chip passive

Deliver message by voice is the most important, effective and common method of exchange information for mankind. Language is human specific features and human voice is commonly used tool which is also the important way to pass information to each other. The voice has large information capacity. So we can use modern method to study voice processing technology, so that people can easily transmit, store, access and apply the voice. In this thesis, we designed a collection system that can collect voice and use different filters to filter the noise. After filtering the noise, the voice will be more

In wireless transceiver circuits some of the most prevalent required off-chip components are discrete filters. These components are generally implemented with surface acoustic wave (SAW) or ceramic components. These devices are used in the receiver section for discrimination of incoming radio frequency (RF) signals as well as downconverted intermediate frequency (IF) signals. Presently, with the growing demand for multi-functional wireless consumer devices, the need for full integration of RF and logic circuits in wireless communications systems is becoming increasingly evident.

The purpose of this thesis is to formulate a technically sound approach to designing Infinite Impulse Response (IIR) digital filters using high-level modeling tools. High-level modeling tools provide the ability to build and simulate ideal models. Once proper validation is complete on these ideal models, the user can then migrate to lower levels of abstraction until an actual real world model is designed. High-level modeling tools are the epitome of the top-down design concept in which design first takes place with the basic functional knowledge of a system. With each level of abstraction, val

As wireless devices and radar systems become more ubiquitous, there is a growing need for wideband multi-standard RF-SOCs. To enable the advantages of multi-standard systems, reconfigurable RF front ends are needed. Because of the large number of RF signals in wideband systems, tunability and linearity become important parameters. Prior work has shown tunable LC filters to be advantageous in the microwave regime.

Low-Earth orbits are considered because the torque used for satellite control is supplied with magnetorquers, and the closer the satellite is to Earth’s magnetic field the more control gain can be supplied. Also, this is the expected orbit altitude of future CubeSat constellations to enable communications. Controlling a CubeSat relies on attitude determination. This means being able to estimate its attitude relative to a given reference frame. To determine the attitude, we propose to use a star trac

In order to enable high-rate transmission in optical communication systems, it is necessary to have a filter that compensates for chromatic dispersion in optic links, since the dispersion alters the signal in an unwanted way.

“Hardware in the Loop” (HIL) testing is widely used in the automotive industry. The sophisticated electronic control units used for vehicle control are usually tested and evaluated using HIL-simulations. The HIL increases the degree of realistic testing of any system. Moreover, it helps in designing the structure and control of the system under test so that it works effectively in the situations that will be encountered in the system. Due to the size and the complexity of interaction within a power network, most research is based on pure simulation. To validate the performance of physical gene

This master‘s thesis focuses on optimization of power and control circuits of an inverter, which was developed at UVEE. The principle of function and circuit implementation of a single-phase inventer, various calculations (design of an LC filter, DC link capacitor, semiconductor elements and heat sink) are described in the thesis. A design of fast overcurrent protections, oscillator and saw signal generator is included. Furthermore, a printed circuit board was designed which was optimized by thermal simulation in the Workbench Ansys. Subsequently, the printed circuit board was mounted, debugge

This thesis deals with design and realization of acoustic camera for sound source location. The essence of the device is microphone field listening for acoustic impulses which are processed in real-time in order to locate the source. Found location is displayed on LCD together with images from regular video camera. FPGA is used as a computational unit.

The diploma thesis is focused on design and optimalization of digital octave and fraction-octave band filters. This thesis describe the behavior of filters in systems with fixed point arithmetics and investigate the impact of quantization coefficients for frequency response of filter. Filters, whitch has been designed, are implemented into simple software in C. Designed filters are in accordance with standard IEC 61260.

The automation revolution already helps in many tasks that are now performed by robots. Increases in the complexity of problems regarding robot manipulators require new approaches or alternatives in order to solve them. This project comprises a research in different available software for implementing easy and fast visual servoing tasks controlling a robot manipulator. It focuses on out-of-the-box solutions. Then, the tools found are applied to implement a solution for controlling an arm from Universal Robots. The task is to follow a moving object on a plane with the robot manipulator. The re

This thesis focuses on detection algorithms of radar targets, namely on group of techniques for removing of disturbing reflections from static objects - clutter and for suppression of distortion products caused by the phase noise of the transmitter and receiver. Methods for distortion suppression in received signal are designed for implementation in the developed active multistatic radar, which operates in the code division multiplex of several transmitters on single frequency. The aim of the doctoral thesis is to design, implement in tool for technical computing MATLAB and analyze the effecti

This master thesis is based on realization of the previous university project, design of locomotive reconstruction and solving accompanying problems. In this thesis there are described all parts of a converter. The end of thesis involved theory about driver circuits of power transistors IGBT. Nowadays is still more often to think about reconstruction of the old technology rather than design a complete new construction. Investors take this decision from the financial reasons and because to the old technology designer can add only the converter. In this instant we talk about electrical locomotiv

The dissertation thesis deals with a study of an influence of a simultaneous incidence of an additive thermal noise and a multiplicative phase noise on the useful signal transmission in narrowband satellite communication systems. While the additive thermal noise affects the useful signal only on the receiver side of the communication system, the multiplicative phase noise is produced in all system oscillators. One investigates how the receiver filter bandwidth reduction takes effect on the influence of individual noise types. The thesis is divided into four units. The first one (chapters 4 and
