Course Description
The basic measurement methods and instrumentation in communication systems are introduced with an emphasis on radio frequency and microwave measurements, propagation measurements and measurements of basic system parameters such as BER, EVM, constellation diagram, system throughput and similar. Particular emphasis of the course is on the practical work of students, which covers examples of measurements of basic parameters of circuits and systems in communications and electronics. Based on the theoretical and practical knowledge acquired, students will be able to measure all the basic measurement quantities that occur in everyday engineering practice in radio communications and electronics.
