non-periodic
Without recurring pattern
Non-periodic describes something that doesn't repeat at regular intervals.
A non-periodic signal lacks a consistent pattern; non-periodic phenomena occur irregularly rather than cyclically.
In mathematics, a non-periodic function never returns to the same values at fixed intervals: The decimal expansion of pi is non-periodic.
Also spelled nonperiodic.
