from Wikipedia, the free encyclopedia

The periodicity , rotation or recurrence generally denotes the property of a thing or a process that has a regularity with regard to the occurrence of a certain event. The regular series of events is a cycle. Meyers Großes Konversations-Lexikon from 1908 writes that periodicity is “the regular recurrence of certain phenomena after a certain period of time, as it is e.g. B. can be observed in the cycle of the seasons. ”The period of time between two identical phenomena of a repetitive process is called a period .

In the case of a temporal periodicity, the frequency makes a statement about how often the event is repeated in a certain period of time, or the period duration (often just: period ) about how long the time period between two events is. In the case of temporal periodicity, the term cycle is also used colloquially for period.

The opposite concept to periodicity is called aperiodicity . Processes that are not periodic are referred to as aperiodic.
