Why do you need to study this course? In recent years, the world has seen a massive surge in use of various forms of communication systems

All the communication systems including user terminals are operating based on their respective underlying communication technologies

Although these technologies are changing very rapidly all of these technologies are using somerapidly, all of these technologies are using some fundamental concepts of communication theory

This course will focus on the fundamental concepts of electronic communications

An Electrical Engineer must have the basic concepts of communications

7

Learning Outcomes Develop a solid background on the fundamental

concepts of analog and digital communication g gtechnologies

The fundamental knowledge gathered from this course will help you

to understand other communication courses in the upcoming semesters and postgraduate studies

to pursue research in communications to pursue research in communications to work in communication sectors
