Question

What is the difference between amplifier and the repeater?

Answer 1

Explanation:

Repeater:

• It is used for the regeneration and transmission in case the previously transmitted signal is weak .
• It takes higher input power , to provide lower output power .
• It uses a static environment .
• It is used for the reduction or elimination of noise .
• It works on the the physical layer of OSI model.

Amplifier:

• It is basically used to increase the amplitude or the strength of the signal .
• It takes lower input power , to provide higher output power .
• It uses in a mobile and remote network .
• It  increases the amplitude of the signal of noise .
• It works in wireless communication .
