Principles of Communication

Principles of Communication

In today’s world, life is not possible without communication. Most of the time we are engaged in any kind of communication like communicating with mobile, Internet etc.,  Now question is that, how this communication happens? What are the processes and devices involve in communication? Answers of your all questions are available in this course. This course will give you a lot of information about communication systems and processes. This course runs in various universities with different names like- Principles of communication, Communication Engineering, Analog Communication etc.
