TelecommunicationsLaajuus (3 ECTS)

Objective

The student understands the basic principle of pulse code modulation. The student knows fundamental limitations for information transmission and characteristics of different transmission channels. The student gets a basic understanding of communications networks and their operation. The student will be able to estimate feasibility of different transmission methods and media for a given communication demand. The student is familiar with different modulation methods as well as modulators and demodulators. He/she understands the communication principles between computers.

The contents and the assessment criteria of the course may be slightly different depending on the teacher of the course.
