New GCEs for 2008
GCE Electronics (2430)
AS outline
At AS, this specification will emphasise the skills and processes of Electronics. Candidates will be given the opportunity to develop their constructional and communication skills. The specification reflects up-to-date practice in Electronics and encourages safe practice in using electronic systems.
The AS specification has 3 units:
Unit 1: Introductory Electronics
Topic list
- System synthesis Voltage, current, resistance and power Diodes Resistive input transducers Transistors and MOSFETs Output devices Op-amps Logic gates and Boolean algebra including the design and simplification of combinational logic systems.
Assessment
| Written Paper: | 1 hour |
| Weighting: | 35% of the total AS Level marks |
| 17.5% of the total A Level marks |
Written Paper – 67 marks, 6 or 7 compulsory questions of varying length.
Unit 2: Further Electronics
Topic list
- capacitors, dc RC networks and timing subsystems
- sequential logic subsystems, counter subsystems, the operational amplifier and amplifier and power amplifier subsystems.

Unit 3: Coursework
Practical skills
Candidates will be expected to:
- identify a problem, consider alternative solutions, conduct research into performance parameters, construct, test and modify the system and produce a report of all of the stages of the development. The report produced should detail all of the development and include photographic evidence of the artefact.
Assessment
| Weighting: | 30% of the total AS Level marks |
| 15% of the total A Level marks |
Coursework – 50 marks. Based on the content of AS units 1 and 2.
In producing the coursework candidates should identify a specific problem to be solved. Consider alternative solutions and give reasons for selecting the solution they have chosen. They should then conduct research so that a list of performance parameters can be provided. They should then construct the system, using at least 3 active devices and test the system. The report produced should detail all of the stages of the development.
