The signals have to travel a long distance which results in reducing their original strength. Hence to increase its strength, amplification is done.

It is necessary to amplifier signal before transmission, because -
• The main reason behind a signal transmission is to send the signal from the transmitter to the reciever.
• Now,the distance between the signal transmitter and signal reciever is often longer than the ideal cases.
• That's why amplification is necessary to boost up the transmission range signal to make it capable to travel the long distance without loosing major amount of energy.
