Course evaluation:


In order to be eligible for a first cycle course the applicant needs to fulfil the general and specific entry requirements of the programme(s) that has the course included in the study programme.

Course specific prerequisites

Courses in Linear Algebra (LMA212), Calculus (LMA22), Electrical Circuits (LEU470), Electrical Engineering (LEU460), as well as Transforms and Linear Systems (SSY020), or corresponding skills.


High speed transfer of information requires electronic circuits operating at higher and higher frequencies. However, at high frequencies, the common theory based on Kirchhoff¿s rules does not apply anymore: The voltages and the currents must be treated as waves. This requires knowledge in the physics of waves, in particular voltage and current waves travelling along transmission lines.
Moreover, the message to be sent from a transmitter to a receiver must have a form suitable for transmission with the chosen technology and medium. This is treated in Modulation theory.
The course aims at students acquiring a good knowledge about basic concepts, principles and methods used in the area of Telecommunication. This provides a good basis for further studies in analog and digital communications (in particular at high frequencies).

Learning outcomes (after completion of the course the student should be able to)

  • descibe concepts and terminology used in this particular field of technology so she/he can study relevant litterature and discuss problems with engineers working in this field

  • describe the propagation mechanism, as well as formulate, analyze and apply simple mathematical models for the propagation of voltage och current waves along transmission lines

  • determine line parameters using laboratory work

  • describe how waves are reflected and how reflections can be eliminated, and perform impedance and reflection calculations (in particular using the Smith chart and the bounce diagram)

  • describe how waves propagate in an optical fiber, and how dispersion affects the transfer of information

  • describe the principles for analogue and digital modulation techniques, and discuss their advantages and disadvantages

  • describe the working principles of electronic components and circuits used for modulation

  • describe various multiplexing methods

  • analyze (using theory as well as laboratory work) and determine wave forms and amplitude spectra of modulation signals , and perform calculations on block diagrams of circuits for modulation and demodulation
  • Content

    Concepts and principles from wave physics and geometric optics. Propagation of TEM waves in free space. Propagation of voltage and current waves in transmission lines. Propagation of light in optical fibres. Transmission line theory: line parameters, impedances, reflections, impedance matching techniques, transients and multiple reflections. The Smith chart and the bounce diagram. Analogue and digital signals. Analogue modulation methods:theory and circuits for the AM, FM and PM techniques. Mixer. Frequency multiplier. Phase-locked loop (PLL). Superheterdyne receiver. Introduction to digital modulation methods: PCM, ASK, FSK, PSK and QAM techniques. Multiplexing methods.


    The course consists of lectures, problem solving sessions and laboratory work.


    To be determined


    Written exam. Compulsory presentation of results from laboratory work. To pass the course both a passed exam and passed laboratory work are required. The final grade is based on the results of the written exam.
