nonperiodic
Lacking regular intervals
Nonperiodic describes something that doesn't repeat at regular intervals.
A nonperiodic signal or pattern lacks the recurring cycles that define periodic phenomena.
In mathematics and physics, nonperiodic functions never return to the same state: The tiling was nonperiodic, with no repeating sections.
Aperiodic means the same thing.
