Introduction As a general concept, the power describes the speed at which a certain amount of energy is released/transmitted by a system. This energy can be of different forms: kinetic, magnetic, electric … etc In any domain, the power is therefore expressed as a quantity of energy per unit of time. The international unit for […]

Introduction When we are listening to a song, we perceive the sinusoidal sound waveforms as music. Their amplitude gives us how loud the signal is and the frequency tells us if the sound is low or high pitched. However, the third important parameter, which is the phase, is harder to experience by ears. This tutorial […]
