What is the process of increasing the strength of a signal?

Explanation:
Amplification is the process of increasing a signal’s strength. In electrical systems, signals have information carried by their voltage or current levels, and making a weak signal usable often means boosting its amplitude. An amplifier is the device that performs this boost, delivering a stronger version of the same waveform. Amplitude refers to how strong the signal is at a given moment, not the action of increasing it. An attenuator, by contrast, lowers the signal strength. So the operation described here is amplification.
