Post-ringing is the oscillatory overshoot that follows a transient in a dynamic system's response. Parameters: (1) the transient trigger (impulse or step input), (2) the amplitude envelope of the overshoot (typically decaying), (3) the frequency of oscillation (determined by the system's resonant modes), (4) the decay rate (damping coefficient). Persistence: observable as damped oscillation in measured signal waveforms after the main transient; recorded in time-domain measurements and simulation. [formal: postannulus | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

- cmrssifjh00bk145rcznrefirINSTANCE_OF →
Post-ringing is a specific signal processing artifact characterized by transient overshoot after a step change. Like pre-ringing (which was previously accepted as INSTANCE_OF artifact), post-ringing is correctly classified as a type of artifact — a byproduct or unintended consequence of a processing technique.
- cmsp1itep03r1jlss77l8np5tDEPENDS_ON →
Post-ringing is the trailing portion of an impulse response after a transient. Remove the concept of impulse response and post-ringing has no mechanism to describe — it IS a feature of the impulse response.
- linear-phase-filterDEPENDS_ON →
Post-ringing is the trailing oscillation produced by the symmetric impulse response of linear-phase filters. Remove linear-phase filters and the specific mechanism generating post-ringing disappears; the artifact stops operating as defined.
- cmsp7zje004gfjlss0ltmm8i4INSTANCE_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.
