Retired. This is not a bibliographic entry. Our extractor captured an inline prose definition from an article and stored it as a work. The concept is real; this registry record is a parsing defect. This entry is kept so the citations that pointed at it still resolve, and so the correction is visible rather than silent.

Mechanisms¶
- Exponential Leaky Integrator
- Because old events fade rather than vanish, a burst leaves a long exponential tail: the estimate stays elevated well after the burst is over, and a step change is approached only asymptotically, never reached, so the integrator systematically lags a rising signal.
This sourceLike an RC circuit charging toward a new voltage, it approaches a step change asymptotically with a fixed time constant, which is why it never fully catches up to a sustained shift and always lags a rising input.
