The objective of the first part is to present the nature of noise generated by electronic devices. The unit explains in detail how electronic noise is generated and measured, and how electronics design can be conducted in order to achieve noise immunity and minimize electronic noise generation. In the Electromagnetic Compatibility part, the phenomena governing extrinsic noise and interference are explained. The students are also introduced to the practical considerations of EMC legislation, test planning and equipment used in test labs. This section also describes electrostatic charge accumulation, methods of discharge, ESD prevention and testing. The aim of optoelectronics is to present the study and application of electronic devices that source, detect and control light. The unit explains in detail the nature of optoelectronic devices and how these devices can be used in electronic circuits. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be: - Able to characterize and distinguish between different noise sources in an electronic circuit. - Able to explain the different noise measurements. - Able to explain the different noise interferences mechanisms. - Able to understand different ways in which EMI may affect a circuit. - Able to know about the different certification authorities and standards classification. - Able to explain what is required from an EMC test plan. - Be familiar with basic equipment used in EMC testing. - Able to describe the principles of operation of different optoelectronic devices. - Able to explain the different optical technologies that constitutes an optical communication system. 2. Skills: By the end of the study-unit the student will be able to: - Design electronic circuitry fit for a purpose in the context of noise emissions and immunity. - Use the electronics analogue and digital circuit design techniques for emissions control and noise immunity. - Enhance the PCB layout design techniques for emission control and immunity. - Use industrial design practices for EMC testing and compliancy.
