Problematika amplitudových diodových modulátorů

Abstract

The main purpose of my baccalaureate work was concerned about the explanation of the problems of amplitude diode modulators, and also about the detailed structure of substantial amplitude modulation. My work is divided into eleven parts. The first part contains the introduction. The second part is addicted to division of the kinds with detailed discription of the main differences. The third part refers about the basic conception of amplitude modulation with dual side band, and the fourth part about the basic conception of amplitude modulation with reduced carrier band. The fifth part is addicted to single side band amplitude modulation, and ways of its formation. The sixth part is one of the most importantly parts of my work, detailing the basic realisation and kinds of the amplitude modulation by amplitude diode modulators. The method of the demodulation is described in the next two chapters. The ninth part includes the basic realisation of amplitude diode modulators, measuring their transitionaly characteristic, and the simulation of amplitude modulation, and also the comparing of the measured and simulated results. The last but one part of my work describes the basic component, the diode, and also includes the description of its siutable selection for using it in the modulators. The target analysis is the pivotal mark of the part eleven.
