Signal Amplifier | Repeater | Regenerator | Difference between Amplifier, Repeater and Regenerator

Amplifiers, repeaters, and regenerators are devices used in communication systems to improve or restore signals, but they differ in their functionalities and the extent to which they process signals:
Amplifier:
An amplifier is a device that boosts the strength or magnitude of an electrical signal without significantly altering its other characteristics like frequency or shape.
It increases the amplitude of the signal, which helps to overcome losses in transmission lines or to compensate for attenuation (weakening) that occurs over long distances in cables or transmission mediums.
Amplifiers are commonly used in audio systems, radio communications, and various electronic devices.
Repeater:
A repeater is a device that receives a signal, amplifies it, and then retransmits the amplified signal to extend the reach or range of a communication system.
It's used in telecommunications to regenerate and retransmit signals in order to maintain their strength and integrity over long distances.
Repeaters are often used in networks, such as in wireless communication (like Wi-Fi or cellular networks) and in wired communication (like Ethernet), to extend the coverage area or the length of a transmission line.
Regenerator:
A regenerator is a device that not only amplifies the signal but also completely reconstructs and regenerates the original signal.
It goes beyond amplification by reshaping the waveform, restoring the signal to its original strength and shape, effectively eliminating noise and distortions that might have accumulated during transmission.
Regenerators are commonly used in optical communication systems to restore optical signals that have degraded due to attenuation or distortion during long-distance transmission through optical fibers.
