This course gives students an introduction to the basic building blocks of modern communications systems. The student is taught the basics of analog and digital modulation techniques and the principles underlying the transmission of information signals from the transmission end to the receiver through a communication channel.

Learning Outcomes
At the end of the course, students should be able to:
- explain the basic building blocks of a digital communication system;
- understand the principles of operation and application of a representative range of communications and broadcasting systems;
- demonstrate a knowledge and understanding of communication principles, including analogue and digital signals, the radio spectrum, modulation techniques;
- apply a systems approach to the analysis and design of communication systems;
- show confidence with the use of measurement equipment such as signal generators and oscilloscopes;

A. Course Introduction

Winding machines. Hoists. Winder trucks. The mining environment. AC and DC mine winders and their controls. Lilly hoist controller and safety systems. Servomechanisms.
C. Course Objectives
The objectives of this course are to: i. Elaborate on concept and principles of haulage machinery in mining and non-mining environment; ii. Highlight the principle of operation and control of mine winders and industrial conveyor systems; iii. Explain signalling and telecommunications in industrial set-ups; and
iv. Outline the principle of operation of servomotors and servomechanisms.
D. Course Outcomes
At the end of the course students will:
i. Have a thorough understanding of the fundamental concepts and techniques used in electrical aspects of
haulage machinery;
ii. Understand the principle of operation of various haulage machinery; and
iii. Acquire the skills to analyze and design electrical systems for electric haulage machinery.
