Comparison and Difference between Amplifier and Repeater

1. The amplifier will amplify signal and increase the voltage of whatever it is that they receive. Repeaters will first decode the signal and extract only the data. They will then regenerate and resend it the destination with the power gain.

2. If the signal has noise with it than amplifies with amplify the overall signal including noise whereas repeater will first decode the signal and extract original data and after eliminating noise repeats the signal.

3. In amplifiers, Using a large number of amplifiers will increases the noise and decreases the signal to noise levels while repeater maximizes signal to noise ratio and gives the cleanest received signal with fewest error bits.

4. Amplifier is one of the part in the repeater.

What are Repeater ?

A repeater is a device that operates only in the physical layer. Signals that carry information within a network can travel a fixed distance before attenuation endangers the integrity of the data. A repeater receives a signal and, before it becomes too weak or corrupted, regenerates the original bit pattern. The repeater then sends the refreshed signal. A repeater can extend the physical length of a LAN.
