Digital Electronics

Course details

Learning Objectives:

This course equips participants with practical “Hands-on” skills relevant to the workplace and the theory required for certification. Participants can expect to have the skills to: –

• Build and fault-finding a range of Digital Electronic circuits used in computers and computer controlled equipment
• Use test equipment including Multimeters, Oscilloscopes, logic probes and pulsers to implement systematic fault-finding techniques.
• Study and use of popular Digital Electronic gates and more advanced circuits

• Practical study of Digital I.C.s including AND, NAND, OR, NOR, X-OR, X-NOR, Inverter, Buffer, SR Latches and D-Latches and Flip-Flops.
• Oscillators, Multivibrators and 555 Timers. Switches and Switch De-bounce circuits and their applications.
• Numbering systems, TTL and CMOS technologies
• Counters, Counter Decoding Circuitry, Shift Registers
• A-D and D-A converters
• Digital Displays: – LED and LCD, numeric and alphanumeric, operating currents, voltages and power requirements. Display decoders and drivers.
• Test Equipment: – Practical use of Analogue and Digital Multimeters, Oscilloscopes, Logic probes, Logic Pulsers, etc.
• Fault-finding techniques: – Diagnosing and rectifying faults on circuits built during course.
