Description

This unit builds upon fundamentals of electrical engineering and introduces students to advanced topics in electrical networks. Appropriate simulation tools are used extensively both as demonstration and problem solving tools. The concept of the transmission line is introduced, and its applications in real-world engineering systems are discussed. This is followed by investigations of general single- and multi-port electrical networks and electrical filters. Passive and active RC filter implementations are also considered.

Prerequisite Rule

Students must pass 2 units from ENS1253, MAT1236

Equivalent Rule

Unit was previously coded ENS2455

Learning Outcomes

On completion of this unit students should be able to:

1. Analyse transmission line circuits and design simple transmission line systems.
2. Apply appropriate simulation software to the analysis and design of electrical networks.
3. Derive and make effective use of single- and multi-port network matrix parameters.
4. Design passive lowpass, highpass, bandpass, and bandstop filters with Butterworth, Chebyshev, Cauer, and Thomson responses.
5. Design simple active filters using ideal operational amplifiers.

Unit Content

1. Filter approximations and passive implementations: Butterworth, Chebyshev, Cauer and Thomson approximations, ladder networks, time-domain considerations.
2. Fundamental concepts of electrical filters: network functions, types of filters, frequency and impedance denormalisation.
3. Selected advanced filter topics.
4. Simulation and analysis tools for electrical networks.
5. Single amplifier active RC filters, second and higher order filters.
6. Single- and multi-port networks: series and parallel connection of networks, cascading networks, basic matrix parameters, scattering parameters.
7. The Smith chart: reflection coefficients, impedance and admittance transformations, parallel and series connections, impedance matching.
8. Transmission line analysis: equivalent circuits, line equations, lossless and lossy lines, termination conditions.

Additional Learning Experience Information

Lectures, tutorials and laboratory sessions (in small teams).
