Amplitude variations

Amplitude variations refer to changes in the strength or intensity of a signal, sound, or wave over time. In simple terms, imagine how loud a piece of music can get: when the sound is really strong and intense, that's high amplitude, and when it's softer, that's low amplitude. In various fields, like physics or audio engineering, understanding these variations helps in analyzing how signals behave, how they can be modulated, and how we perceive sounds and other forms of energy. Essentially, amplitude variations are about the fluctuations in the power of a wave or signal.
