DIGITAL ELECTRONICS COURSES
This course is designed to give a practical knowledge of the type of electronic circuitry which is used in a Computer System or in any type of Computer Controlled equipment such as Photocopiers, Cash Registers, etc. Digital Electronics involves the use of Silicon chips (Integrated Circuits). The internal structure of a computer is to a large extent comprised of Digital Electronic Circuits.
To enable participants to build, test, and fault-find common Digital Electronic circuits used in computers and computer controlled equipment.
- City & Guilds of London Institute Digital Electronics 2 (Examination No. 7267-425). This examination consists of 1 written paper and 4 practical assignments. The qualification can be used as part of the requirement for City & Guilds Diploma in IT Systems Support (7267-24).
- On completion of the Course, having been successful in an examination, the participant will receive a Hi-Tech Training Certificate.
