Ringing is the concept of sustained oscillations that persist in a dynamic system's output after a transient disturbance has ended. It manifests when a system with overshoot exhibits underdamped behavior, causing the response to oscillate around the steady-state value before gradually decaying. Ringing is characterized by three parameters: (1) the decay rate (determining how quickly oscillations diminish), (2) the oscillation frequency (typically the system's natural resonant frequency), and (3) the initial amplitude (determined by the overshoot magnitude). The persistence mechanism is the mathematical model of underdamped second-order systems (differential equations with complex conjugate poles) and empirical observation in physical systems including electrical circuits, mechanical structures, and acoustic resonators. The concept is used by engineers to diagnose system stability, by physicists to analyze damped harmonic motion, and by signal processing practitioners to understand transient behavior in filters and measurement systems.

Definition
Why it is in scope
Ringing is the human concept of sustained oscillations that persist after a transient disturbance in a dynamic system. It arises when a system has overshoot and insufficient damping, causing the output to oscillate around the steady-state value before settling. Engineers and physicists model ringing as the underdamped response of second-order systems, and it is a practical concern in electronics, control theory, and acoustics where unwanted oscillations can degrade performance or cause damage.

Ringing is a specific kind of oscillation — sustained oscillation after a transient. A competent speaker would call ringing 'a type of oscillation.' Per Law 9, this is INSTANCE_OF, not DEPENDS_ON: it's about kind-of membership, not operational dependency.
- cmsoyq4kf03g2jlss6cfwbvj6DEPENDS_ON →
Ringing is defined as sustained oscillation that occurs AFTER a transient in a system. The transient is the initial response that triggers the oscillatory behavior. Remove the transient and ringing ceases to operate — there is no 'after the transient' without the transient. This passes the removal test (Law 8): ringing's operation requires the transient as its starting condition.
- cmsohgmvz01mkjlssemttvpeiDEPENDS_ON →
Ringing is a damped oscillatory phenomenon — the oscillatory overshoot and decay that follows a step input or impulse. Remove the concept of oscillation and ringing as a concept ceases to operate: ringing IS oscillation with damping. The removal test passes at the object level.
- cmsoyklv703fijlssqta8v3rjDEPENDS_ON →
Ringing is specifically sustained oscillation in underdamped systems. Remove the concept of damping and the ringing concept — as underdamped oscillation persisting after excitation — ceases to operate. The underdamped/overdamped distinction is fundamental to defining what ringing is.

- pre-ringing← INSTANCE_OF
Pinned sense (Law 11d): ringing as the family of oscillatory overshoot around a transient in a dynamic system, where the before/after orientation of the transient is a parameter of the member, not the family boundary. Pre-ringing is the before-the-edge member of that family: sustained oscillation preceding a step, produced by the same underdamped / two-sided-impulse-response mechanism that produces post-ringing afterward. The is-a test (Law 9) passes in the pinned sense — a competent audio engineer calls pre-ringing a kind of ringing; the name itself is 'pre-' + 'ringing', and the DSP literature treats pre- and post-ringing as the two orientations of one phenomenon. Nearest kind is ringing: not 'artifact' (its accepted definition carves deliberately crafted objects with material substrate and intentionality — pre-ringing is a byproduct, the sense that got my INSTANCE_OF there struck); not 'overshoot' (the excess amplitude, a parameter of the ringing, not its genus).
- post-ringing← INSTANCE_OF
Post-ringing is the specific kind of ringing that occurs after a transient trigger. The ringing family covers oscillatory overshoot around transients; post-ringing is the after-orientation member, distinguished by temporal position relative to the transient.
