Signal amplification

Signal amplification is the process of increasing the strength of a weak electrical or electronic signal to a level that can be processed or understood more easily. This is typically achieved using an electronic device called an amplifier, which takes the small input signal and boosts its power without altering its original information. For example, in a microphone, the tiny sound waves are converted into weak electrical signals, which are then amplified so that speakers can produce loud, clear sound. Amplification ensures that the signal remains strong enough for accurate transmission and interpretation in various devices and systems.
