space communication involves sending signal emitted from the antenna of the transmitter to the antenna of the receiver. describe in brief. mentioning frequency range of the operation four different ways by which space communication become possible.
Answers
Explanation:
Space communication involves sending signal emitted from the antenna of the transmitter to the antenna of the receiver. ... For example, broadcasting, mobile radio, or navigation devices, will be allocated in non-overlapping ranges of frequencies.
Television broadcast & Microwave links
Explanation:
During space communication a signal is transmitted in space using transmitter antenna and is received by receiver antenna by intercepting the signal that is carried by wave propagation. This wave travels in a straight line flowing from transmitting antennae to receiving antennae.
Examples of communication system that use space wave mode of propagation are as follows -
- Television broadcast
- Microwave links
- Satellite communication
When an electricity flows through the transmitter antenna it makes the electrons to vibrate that produces radio waves.
The speed of the radio waves is equal to the speed of light there fore it travels at the same speed of light.
Frequency range of radio waves is as follows -
Band Frequency
S - 2110 - 2120
X - 7145 - 7190
Ka - 34200 - 34700
