What is space wave propagation?
The radio waves having high frequencies are basically called as space waves. These waves have the ability to propagate through atmosphere, from transmitter antenna to receiver antenna. These waves can…
What is Microwave Propagation?
Electromagnetic waves having frequency greater than that of the television signals are known as Microwaves. These waves have very less wavelength nearly few millimeters. Due to their low wavelength, these…
What is Remote Sensing?
To measure the characteristics of an object from a distance, the technique of remote sensing is used. By this technique we can collect all information about an object without making…
Explain the different losses in Transmission lines?
The energy losses that happen in case of transmission lines are shown below: 1. Conductor Heating 2. Dielectric heating 3. Radiation Losses It is observed that the radiation loss in…
What is Satellite Communication?
In satellite communication, signal transferring between the sender and receiver is done with the help of satellite. In this process, the signal which is basically a beam of modulated microwaves…
What is Line Communication?
In line communication there is a physical connection between source and destination. The wired connections between two points are known as transmission lines. The wires that are most popular for…
Explain the equivalent circuit of a transmission line?
We know that the conductors are present in a two wire line. Dielectrics are also present between them. It is also clear that conductors can be of any length. Conductors…
What is Cable System?
Cable system is basically a collection of no of co-axial lines enclosed together in a tube or pipe. This cable system also consists of other useful things, along with the…
What are Telephone Links?
In today’s fast world, telephone is a necessity. Telephony is not limited to earth. We can also converse from earth to any other planet e.g. moon, mars etc. It depends…
