One More Tool for Understanding Resonance and  the Way for a New Definition

<table>The definition of resonance [<a href="/journals/je/2013/414109/#B1">1</a>] as <i>linear increase of the amplitude</i>. (The oscillations fill the angle of the envelope.) The <i>infinite</i> process of increase of the amplitude is obtained because of the assumption of <i>losslessness</i> of the system.</table>
