Periodic Function

Pronunciation: /ˈpɪəɹ.ɪ.əd.ɪk ˈfʌŋk.ʃən/ Explain

A periodic function is a function whose values repeat over a specific interval. The interval over which the output of the function repeats is called the period of the function. The frequency of a periodic function is inversely proportional to the period: . Frequency is usually measured in cycles per second (cps). The amplitude of a periodic function is half the distance from the minimum to the maximum values in the range. In nature, the amplitude of a wave is related to the energy of the wave.
