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 ...
In analog electronics, Clock feedthrough is the result of the coupling between control signals on the analog switch and analog signal passing through the switch. In digital electronics, clock feedthrough is the coupling of the clock signal to the nodes where coupling is not intended.
An improved technique for preventing this condition is known as adaptive "non-overlap" protection, in which the voltage at the switch node (the point where S 1, S 2 and L are joined) is sensed to determine its state. When the switch node voltage passes a preset threshold, the time delay is started.
The sinc function, the impulse response for an ideal low-pass filter, illustrating ringing for an impulse. The Gibbs phenomenon, illustrating ringing for a step function.. By definition, ringing occurs when a non-oscillating input yields an oscillating output: formally, when an input signal which is monotonic on an interval has output response which is not monotonic.
ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...
Typical Northern Telecom DMS-100 Telephone Central Office Installation A DMS-100, in a CO located in France. The DMS-100 is a member of the Digital Multiplex System (DMS) product line of telephone exchange switches manufactured by Northern Telecom.
Ringtest is also called proficiency test or interlaboratory test. Usually a reference institute sends identical samples which have to be analyzed for special parameters to different laboratories. The industrial, medical or research laboratory gets a limited time with a deadline to send in the analysis results. The statistical evaluation and ...
Damped oscillation is a typical transient response, where the output value oscillates until finally reaching a steady-state value.. In electrical engineering and mechanical engineering, a transient response is the response of a system to a change from an equilibrium or a steady state.
