Description:

The course discusses principles of telecommunication systems - mainly digital transmission systems and digital switching systems - that form the basis of communication networks. It provides students an overview of the entire telecommunication domain, so that they can solve particular problems related to network design and traffic. They will also obtain basic knowledge of selected technologies that are used in modern wired and wireless networks.
