Basic Communication System – Communication Engineering

From the examples of communication discussed so far, now we can prepare the model of basic communication system. We know that for any communication to take place, three things are essential....
An example of communication system

Basic Principles of Communication Engineering

What is Communication ? Communication is the process of establishing connection (or link) between two points for information exchange. In our day to day life we come across many ways of communicate. For...
Series Capacitor

Series Capacitor Voltage – Power System Operation and Control

Series Capacitor It is connected in series capacitor to compensate the inductive reactance of line. This reduces the transfer reactance between the buses to which the line is connected. It increases maximum...

Radio Over Fiber Links – Optical Fiber Communications

Radio over Fiber Links One application of RF radio over fiber technology is in broadband wireless access networks for interconnecting antenna base stations (BSs) with the central controlling office. Image shows the...
Analog Link

Analog Link in Optical Communication

Analog Link In telecommunication networks the trend has been to analog link telephone exchanges with digital circuits. A major reason for this was the introduction of digital integrated-circuit technology which offered a...
Penalty power

Penalty Power in Optical Communication

Penalty Power The analysis in this post assumed that the optical power falling on the photodetector is a clearly defined function of time within the statistical nature of the quantum detection process....
Methods of Voltage Control

Methods of Voltage Control in Power System

Methods of Voltage Control Methods Voltage control level is accomplished by controlling the generation, absorption and reactive power flow at all levels in the system. The following are the methods of voltage control. ...
