What is the difference between Broadband and Baseband Transmission?
Broadband transmission is used for a network in which information is modulated onto a radio frequency carrier which passes through the transmission medium such as a coaxial cable. Broadband transmission allows a number of modulated radio frequency carriers to be … Read more
Data Acquisition and Telemetering in Power Systems
To be able to manage and control a power system, the network engineer requires reliable and current information about the state of the network. He obtains this information from power flows, bus voltages, frequency and load levels along with the … Read more
The Fundamentals of Oscillators in Communication Systems
A communication system consists of an input device, a transmitter, a transmission medium, receiver and output device. The input device can be a computer, sensor or oscillator, depending on the application of the system, while the output device could be … Read more
Basics of Radio Frequency (RF) and Wireless Communication Systems
Radio frequency (RF) is any frequency within the electromagnetic spectrum associated with radio-wave propagation. When an RF current (input signal) is supplied to an antenna, an electromagnetic field is created that is then able to propagate through the space.
RF … Read more
