What do you mean by communication?
1.
The undesired electrical signals are termed as noise. When a signal is transmitted, the undesired signals get mixed with it, leading to distortion of the signal.
2.
The signal wave that results on superimposing the modulating wave on the carrier wave is called modulated wave.
3.
The T.v. signals have frequencies in 100 - 200 MHz. As the ionosphere cannot reflect radio waves of frequency greater than 40 MHz back to the earth so the sky waves cannot be used in the transmission of T.v signals.
4.
It is a combination of receiver and transistor placed along the path of signal so as to extend the range of the communication system.
5.
The communication is the processing, sending and receiving of information with the help of a suitable communication system and transmission medium.
