Ringing

n. sound of a bell, ring

v. call on the telephone (British); bid, call, summon; encircle, surround; form into a ring; sound a bell; seem, appear; resound, be filled with sound; reverberate, echo

Electricity In electrical circuits, ringing is an unwanted oscillation of a voltage or current, also called microphony. It happens when an electrical pulse causes the parasitic capacitances and inductances in the circuit (i.e. those that are not part of the design, but just by-products of the materials used to construct the circuit) to resonate at their characteristic frequency. Ringing artifacts are also present in square waves. Ringy communications circuits may suffer falsing. "The Art of Microphony" is a sometimes heard wrong topic, which never means ringing.
