Course Information

The WJEC have introduced a new syllabus to take account of the rapid changes in the field of electronics. This is a distance-learning course in association with CYNNAL in Llangefni.
Our link tutor is Mr. G. Timms.

This course is an ideal introduction to both the electronics engineering and computer science and for those with an interest in technology. No prior electronics experience is necessary.

The course is split into a number of modules, each module being a mixture of theory and practical exercises, which allow each topic to be investigated fully.

Advanced Subsidiary (AS)

ET 1 Introduction to Digital and Analogue Systems

The unit introduces the use of decision logic systems to produce digital outputs and amplifiers as a method of changing a voltage signal.

E2 Circuits and Components

The unit investigates the function and use of different electronic components and methods of circuit design.

E 3 Control Systems

Mini project, focusing on programming controllers in a high level language.

Advanced Level (AS plus)

ET 4 Communication Systems

Investigates the different methods of electronic communication.

ET 5 System Application

The unit investigates design and construction of systems using the concepts introduced and practical applications of electronics systems.

E6 Project Report

The major project involves planning and developing an electronic system.

Course features

• Covers a wide range of up to date areas of electronics.
• Examinations in January and June
• Course work forms part of the assessment in both AS and A Levels

A good understanding of mathematics is essential.

The course is ideal introduction to the vast area of electronics, for students that may wish to follow either electronics or computer science in further education or for those who wish to work in the technology area.
