摘要:
Simple resonance curves plotted vectorically are approximately circular in form. The paper shows how the circle can be derived from the ordinary resonance curve by a simple graphical construction, and how from the derived circle and the original resonance curve a straight line can be drawn from which the resonance frequency and the damping are at once determined.The constructions developed are explained by their application to telephone-receiver impedances and to electrical circuits.
