Communication Systems
Introduction
[edit | edit source]This book will eventually cover a large number of topics in the field of electrical communications. The reader will also require a knowledge of Time and Frequency Domain representations, which is covered in-depth in the Signals and Systems book. This book will, by necessity, touch on a number of different areas of study, and as such is more than just a text for aspiring Electrical Engineers. This book will discuss topics of analog communication schemes, computer programming, network architectures, information infrastructures, communications circuit analysis, and many other topics.
This book is still in an early stage of development. Many topics do not yet have pages, and many of the current pages are stubs. Any help would be greatly appreciated.
 | Several pages from this book have been moved to Communication Networks and Data Coding Theory. If you are looking for a page that seems to have disappeared, check in these places. |
Table of Contents
[edit | edit source]System Examples
[edit | edit source]This section will provide a brief overview of the more common communications systems in use today. The demarcation between these systems is quite artificial since a wireless VoIP Internet connection may be a combination of all of these individual systems.
- Telephone System
- Cellular Systems
- Packet Data Systems
- Satellite Systems
- Microwave Systems
- Fiber Optic Systems
Communications Basics
[edit | edit source]This section will examine some theory common to many communication systems. Examples are, what constitutes a signal, information, channels, multiplexing etc.
- Baseband and Broadband Signals
- Time-Division Multiplexing
- Frequency-Division Multiplexing
- Voltage-Controlled Oscillators (VCO)
- Envelope Filters (Envelope Detectors)
- What is Modulation?
- Analog vs. Digital

- Coherent Receivers
Analog Modulation
[edit | edit source]This section will examine the nature and conveyance of continuously varying information signals.
- Analog Modulation Introduction
- Amplitude Modulation (AM)
- Frequency Modulation (FM)
