Type of module:

Summary module description:
This module provides a foundation in the theory that supports the understanding of DC and AC (frequency dependent) circuits, and circuits that contain logic elements and Operational Amplifiers (Op-Amps). This module also introduces the analysis and design of such circuits.

Aims:
This aim of this module is to provide students with the background knowledge, theory, skills and tools to enable them to analyse and design simple electronic circuits that consist of the most common components and elements that include voltage and current sources, resistors, capacitors, inductors, logic gates and operational amplifiers.

Assessable learning outcomes:

By the end of the module the students should be able to do the following when given sufficient information:

• Recognise, and describe and apply the theory underpinning, voltage and current sources, resistors, capacitors, inductors, logic gates and operational amplifiers.


• Analyse circuits consisting of voltage and current sources, resistors, capacitors, inductors, logic gates and operational amplifiers, and determine the currents, voltages and pow er outputs of such circuits.


• For AC (frequency dependent) circuits, be able to describe and calculate the behaviour of such circuits in the frequency domain, specifically how the gain of such circuits varies with frequency and also to be able to identify common filter types such as low-pass and high-pass.


• Perform analysis of logic circuits and form, manipulate and simplify logical expressions.


• Analyse circuits that include Op-Amps, including the ap plication of feedback.

Additional outcomes:

Outline content:
