Pre-requisites

Familiarity with op-amp circuits, basic competence with electronic design, competence is the use of simple electronic test equipment including oscilloscope, signal generator and soldering.

Course Summary

This course is an exercise in basic analogue electronic circuit design using discrete components and operational amplifiers. The exercise involves designing analogue circuits for the implementation of an end-to-end optical signal transmission through free-space and a guide plastic optical fibre channel.

Course Description

In this course emphasis will be on hands-on learning through experimentation. The fundamental properties of optical communications will be taught at the start of course; including signal attenuation in fibre, dispersion/pulse spreading and LED/Laser comparison and photo-detection. The course is designed to use knowledge gained by students in the earlier years of their course and aims to act a "structured project". The course is structured so as to act as an introduction to the more open ended type of final year project work carried out in the fourth and fifth years. Until this point in the course the students experience is largely of analysis of circuits supplied to them. In this exercise students are expected to synthesise their own designs and realise their own circuitry.Assessment of this course will be based on: (1) a written report by the students explaining their design and the function of each subsystem. This report will be expected to include the circuit diagrams, design equations and a complete list of components and their values. In addition, the report should contain student attempts to specific questions in the provided laboratory script. (2) The PCB layout, efficient use of space on the PCB, good soldering/component placement on the PCB. (3) Finally, the design functionality. It is expected that, with the implemented design, it should be possible to achieve an end-to-end optical signal transmission over plastic optical fibre and demonstrate LiFi audio signal transmission. Assessment is based on the measured performance metrics stated in the lab manual and quality of the LiFi audio signal transmission.
