Transmission Lines & Complex Waves SCQF Level 8

An introduction to transmission lines and complex waves in relation to electrical engineering.


Why take this course?

This Unit is designed to enable candidates to understand the basic principles and concepts of transmission lines and complex waves. It will provide candidates with the opportunity to develop knowledge and skills to determine electrical quantities associated with transmission lines and secondly, to solve simple electrical series and parallel circuits when a complex waveform is applied. On completion of this Unit the candidate should be able to:
1. Evaluate the characteristics of transmission lines
2. Evaluate performance of transmission lines with matched termination
3. Evaluate performance of transmission lines with various terminations
4. Solve network response problems when complex waves are applied

What you will experience

This Unit has been designed to allow you to develop your knowledge, understanding and skills in the principles and concepts of transmission lines and complex waves.  By the end of the Unit, you should be able to solve through calculation and graphical analysis, electrical quantities associated with transmission lines and secondly, solve simple electronic circuit problems involving complex waveforms.

In Outcome 1, you will be introduced to different types of transmission line. You will also learn how a transmission line can be represented by electrical quantities and how to determine the secondary parameters of a line.

In Outcome 2, you will use the parameters introduced in Outcome 1 to calculate by the use of equations, voltage, current and power in a transmission line with a matched termination.

In Outcome 3, you will use equations and graphical methods to determine values of voltage, current and power for a transmission line with various terminations.

In Outcome 4, you will learn about complex waveforms and how to solve various electrical quantities in an R – L - C and an R – L // C circuit when a complex wave is applied.
Although there is no practical assessment in this Unit, it is likely that laboratory work and computer simulation will be used to support the theory.

The Unit will be assessed by one written assessment at one assessment event. Your lecturer should inform you how the Unit will be assessed. The assessment will take place at the end of the Unit and shall last two hours under controlled, supervised conditions. You will not be allowed to use or refer to any notes or textbooks during the assessment but you will be allowed to use a supplied formulae sheet and a scientific calculator.
