In electrical circuits, ringing is an oscillation of a voltage or current.Ringing can be undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted [citation needed]; it can increase settling time for the desired final state; and it may cause unwanted triggering of ...
Ringing is a telecommunication signal that causes a bell or other device to alert a telephone subscriber to an incoming telephone call. Historically, this entailed sending a high-voltage alternating current over the telephone line to a customer station which contained an electromagnetic bell.
The telephone exchange immediately removes the ringing signal from the line and connects the call. The ringing pattern is known as ring cadence, in which the high voltage ring current is switched on and off to create the pattern. In North America, the standard ring cadence is two seconds of ringing followed by four seconds of silence.
The main cause of ringing artifacts is overshoot and oscillations in the step response of a filter. The main cause of ringing artifacts is due to a signal being bandlimited (specifically, not having high frequencies) or passed through a low-pass filter; this is the frequency domain description.
Sarow says that ringing in one year is known as unilateral tinnitus, and it doesn't always mean a serious condition is present. "There are many potential contributors to this phenomenon, such as ...
