👉 Peakness refers to a characteristic of a signal or waveform, such as the amplitude at its peak or the frequency at which it reaches its maximum value. Peakiness is often used in electrical engineering and physics to describe how much of an input signal has been amplified during a certain period of time. In other words, if you have a sinusoidal wave that starts at a high point and then decays back down to a lower point, the peakness would indicate how much energy was present at its highest
