koherenssivälin
A koherenssiväli, or coherence interval, is a concept used in signal processing and communication systems to describe the time duration over which a signal's properties remain relatively constant or predictable. It is particularly relevant when dealing with signals that are not perfectly stationary, meaning their statistical properties can change over time.
The coherence interval is essentially a measure of the signal's "memory" or how long past values influence
In practical applications, the coherence interval helps determine appropriate sampling rates, filter designs, and the effectiveness
The exact definition and calculation of the coherence interval can vary depending on the specific context
