Digitální modulace v telekomunikacích

Abstract

This bachelor's thesis is focused on overview of digital modulations and their significance in telecomunications. Theoretical part contains importance and usage of modulations in general and short description of analogue and discrete modulations in the baseband. One of the chapters is dedicated to description of discrete modulations with with carrier waves, which are called digital modulations. Practical part is focused on realization of digital modulations using learning system Emona TIMS and simulation program tutor TIMS. First part contains realization of chosen modulations in form of measurement, the instruction and sample protocol. Second part contains manual for measurement of chosen digital modulation. This measurement is focused on new tasks which will be used in practical lessons.
