This thesis develops a novel method to predict radiated emissions measurements. The techniques used are based on standard Electromagnetic Compatibility (EMC) qualification test methods. The empirical data used to formulate the final results was restricted to pertinent data protocol waveforms however the entire method may be applied to any waveforms for which empirical radiated emissions have been measured. The method provides a concise means for predicting worst case radiated emissions profiles based on empirical measured data.<br>M.S.E.E.<br>School of Electrical Engineering and Computer Scien

The aim of this thesis was to develop a model of a receiver which could be quickly used to analyze radiated interference levels from data captured at the output of the antenna equipment used to measure radiated energy. Active circuits were mainly used in developing this model for the ease with which the design and simulations could be carried out in OrCAD. The guiding document for the thesis work has been CISPR 16-1-1 (International Special Committee on Radio Interference part 16-1-1) which specifies the characteristics and performance of equipment for the measurement of radiated interference.

Thesis (MScEng)--University of Stellenbosch, 2005.<br>ENGLISH ABSTRACT: Common mode currents are a major source of interference in electrical and electronic systems. A universal solution to counteract common mode interference is to introduce an electromagnetic shield with known characteristics. Cable trays are often used to shield cables from unwanted electromagnetic interference (EM!) and its shielding characteristics are defined in terms of its transfer impedance. This thesis pursues the modelling and measurement of the transfer impedance and mutual inductance of non-magnetic cable tra

These attacks change the reported value of a sensor so that it doesn't re ect the real situation. The systems in a car can be used as an example of this.

M.Ing.<br>This thesis investigates why electromagnetic interference (EMI) and electromagnetic compatibility (EMC) problems exist and how EMI is generated, measured and limited. This investigation is done with reference to power systems and satellite earth stations. To understand the full extend of EMI generation from power systems on satellite earth stations, it was necessary to do a study of EMI, in order to understand EMI in its simplest form. This study consists of the following work: •A background study investigates the components of EMI, how EMI are generated and manifest in electric syst

Due to working stress and bad gesture, most people usually have the problem of body pain, for example, sore and stiff neck and shoulder. In order to relief the pain, electric massagers have been used widely. Shoulder and neck massager is the one that has to be contacted on human skin during working; the electromagnetic problem then becomes an essential issue that has to be measured and tested. Therefore, the objective of this study is dealing with the electromagnetic interference whic

Moreover, the solution for internal and external interference sources with the difference conditions of a communication system include the location, the environments and the equipments of a communication system are discussed. Besides, the thesis not only study the processes and the device for measuring the interference of a communication system, the choose of the location of a communication system is also analyzed by some physical measured data

碩士<br>義守大學<br>電子工程學系<br>91<br>In this thesis, a PC-based automatic measurement and filter design system for the electromagnetic interference emission of SMR is developed. The man-machine interface is written in LabVIEW graphical programming language. The effort of solving the conductive EMI is greatly reduced by the fast computing speed and the friendly man-machine interface of the PC. The emission measurement and suppression procedure established can accomplish the reduction of the developing period and cost. Not only the production is speeded up, but also the acceptability of the SMR manufac

碩士<br>國立中山大學<br>應用數學系研究所<br>92<br>Open site measurement on the electromagnetic interference is the most direct and universally accepted standard approach for measuring radiated emissions from an equipment or the radiation susceptibility of a component or equipment. A site is qualified for testing EMI or not is decided by the antenna measurements. In this work, we use data from setups with di erent factors to find relations of measurement and the situation of antenna. A one change point model has been used to fit observed measurements and compare the di erences with two kinds of antenna (broadb
