FREQ

FREQ is an abbreviation commonly used to denote frequency in science, engineering, computing, and data analysis. In physics and engineering, frequency refers to the number of cycles of a periodic phenomenon per unit time, usually measured in hertz (Hz). FREQ appears on instruments and software as a label or parameter representing the rate of oscillation, rotation, or modulation. In signal processing, specifying the FREQ is essential for tuning radios, oscillators, filters, and communication systems.

In statistics and data analysis, freq or frequency denotes the count of occurrences of a value or category within a data set. A frequency distribution tabulates these counts; when normalized, it yields relative frequency or probability.

In computer science, FREQ is often used as a shorthand in documentation, variable names, and user interfaces to indicate frequency-related quantities, such as event frequencies, sampling rates, or clock speeds. In music technology, frequency determines pitch; many synthesizers expose a FREQ control to adjust an oscillator's pitch.

While "FREQ" can be encountered as an acronym for organization or project names, its primary meaning remains frequency. If encountering ambiguous usage, context—such as physics, statistics, or electronics—helps determine the intended meaning.
