Fréquence
Fréquence, or frequency, is the rate at which something occurs or repeats over a given period of time. In physics and engineering, it typically refers to the number of cycles of a periodic process per unit time, most often expressed in hertz (Hz), where 1 Hz equals one cycle per second. The angular frequency, measured in radians per second, is related by ω = 2πf.
The reciprocal of frequency is the period: f = 1/T, where T is the time required for one
In signal processing and data analysis, frequency describes the distribution of a signal’s energy across different
Statistically and in linguistics, frequency denotes how often an event or item occurs within a dataset or
