Digital Signal Processing Summary and Vocabulary Guide to Digital Signal Processing by Steven W. Smith. Read up to page 10, preface included. https://users.dimi.uniud.it/~antonio.dangelo/MMS/materials/Guide_to_Digital_ Signal_Process.pdf Digital Signal Processing (DSP) is a powerful technology that will shape science in the twenty-first century. Changes have already been made in various fields of study: communications, medical imaging, and high fidelity music reproduction, to name just a few. Each of these disciplines has developed a deep DSP technology, with its own algorithms and specialized techniques. This combination of breadth and depth makes it impossible for any one individual to master all of the DSP technology that has been developed. Therefore, DSP education involves two tasks: learning general concepts that apply to the field as a whole, and learning specialized techniques for your particular area of interest. The first ch...

Essay How the right of privacy was viewed in the 1890s and 2010s. Comparison between two articles by Warren & Brandeis and Julie Cohen The two articles have questioned - What is privacy ? The simplest answer would be that the privacy is a human right and like in the first article by Warren & Brandeis, they quote Judge Cooly who sayd that, the privacy is the right to be let alone. This means, that a person is free to go and do what ever the person wants, no one has a right to harm him/her physically or mentally and vice versa. What ever the person decides to do, nobody else has the right to know about it without persons premission. Julie Cohen starts her essay with a point that privacy has the image problem. In the world where there is no mobile platforms, data mining social meedia, in simple words the internet, its easyer to leave the person alone, but what can we do in the world where is very difficult to be incognito because ...

VORMISTAMISE ÜLESANNE 2 TUNNITÖÖ Õppeaines: SISSEJUHATUS ERIALASSE Tehnoloogia ja ringmajanduse instituut Õpperühm: Juhendaja: Tallinn 2021 SISUKORD 2 ABSTRACT Pilling is an undesired defect of textile fabrics, consisting of a surface characterized by a number of roughly spherical masses made of entangled fibers. Mainly caused by the abrasion of fabric surface occurring during washing and wearing of fabrics, this defect needs to be accurately controlled and measured by companies working in the textile industry. Pilling measurement is traditionally performed using manual procedures involving visual control of fabric surface by human experts. Since the early nineties, great efforts in developing automatic and non-intrusive methods for pilling measurement have been made all around the world with the final aim of overcoming traditional, visual-based a...
1.The Conceptual Architecture identifies the high-level components of the system, and the relationships among them. Its purpose is to direct attention at an appropriate decomposition other system without delving into details. Moreover, it provides a useful vehicle for communicating the architecture to non-technical audiences, such as management, marketing, and users. Logical Architecture In Logical Architecture, the externally visible properties of the components are made precise and unambiguous through well-defined interfaces and component specifications, and key architectural mechanisms are detailed. The Logical Architecture provides a detailed "blueprint" from which component developers and component users can work in relative independence. Logical Architecture. Model System Behavior Execution Architecture An Execution Architecture is created for distributed or concurrent systems. The process view shows the mapping of components on...

It involves identifying a specific group or category of people and collecting information from some of them in order to gain insight into what the entire group does or thinks; however, undertaking a survey inevitably raises questions that may be difficult to answer. How many people need to be surveyed in order to be able to describe fairly accurately the entire group? How should the people be selected? What questions should be asked and how should they be posed to...
Eksami küsimused: 1. Mida tähendab mitmekiireline levi Mitmekiireline levi – info levib mööda peegeldusi, otselevi on väga harva. Kohale jõuab mitu lainet samaaegselt. Halb, sest lained liituvad (võivad tasakaalustada ennast ning signaal kustub ära, nõrgeneb). Kuna inimene liigub, muutub sagedus – lainepikkus – tuleb kogu aeg kanalit järgi kruttida. 2. Mida tähendab alla- ja üleslüli ning dupleks kaugus mobiilsides Pertaining to computer networks, a downlink is a connection from data communications equipment towards data terminal equipment. This is also known as a downstream connection. The uplink port is used to connect a device or smaller local network to a larger network, or connect to the next "higher" device in the topology. For example, the edge switch connects "up" to the distribution layer managed switch. Lühidalt - The communication going from a satellite to ground is called...
