The foundations of analogue electronics studied in Electronic Engineering 1X are applied to practical circuits such as RC filters and amplifiers based both on integrated operational amplifiers. Discrete semiconductor devices are introduced. Based around programming a modern microcontroller, and interfacing it with peripheral components, the course also introduces the concepts of embedded systems including digital and analogue input and output.

In accordance with the University's Code of Assessment reassessments are normally set for all courses which do not contribute to the honours classifications. For non honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students, and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions are listed below in this box.
It is not possible to offer reassessment in group project work in this course. Students failing to complete the Lab work, without good cause, will be receive a Credit Refused (CR) grade and will be required to re-attend the course the following year.
Main Assessment In: April/May
The aims of this course are to:
■ apply the basics concepts of analogue electronics to practical circuits such as RC filters and amplifiers, based both on integrated operational amplifiers and transistors;
■ give practical experience in programming a modern microcontroller;
■ introduce key concepts of embedded systems, and underpin these by practical example;
■ give practical experience of designing, building and measuring analogue circuits based on operational amplifiers;
■ develop skills in systematic design and documentation.
Intended Learning Outcomes of Course
By the end of this course students will be able to:

■ specify, design and build on stripboard a simple audio amplifier for a portable music player;
■ design and build a microphone amplifier with rectifier and low-pass filter;
Combined digital/analogue laboratories
■ write C programs and design and construct appropriate analogue electronics to demonstrate an application of the students choice running on the mbed microcontroller;

Minimum Requirement for Award of Credits
Students must attend the degree examination and submit at least 75% by weight of the other components of the course's summative assessment.
Students must attend the timetabled laboratory classes.
Students should attend at least 75% of the timetabled classes of the course.
Note that these are minimum requirements: good students will achieve far higher participation/submission rates. Any student who misses an assessment or a significant number of classes because of illness or other good cause should report this by completing a MyCampus absence report.
