pulsés

Pulsés is a French adjective and past participle used to describe phenomena that occur in pulses or are driven by pulses. In technical writing, it qualifies signals, modes, or processes that are not continuous but delivered as bursts or intervals.

Etymology and usage notes emphasize that pulsés is the masculine plural form; feminine plural would be pulsées. The term derives from Latin pulsus, through French, and is related to pulsation, the noun denoting the act or process of pulsing. In many contexts, pulsés serves as a concise modifier to indicate a non-continuous or burst-like character.

In practice, pulsés appears across several domains. In electronics and signal processing, a signal pulsé denotes a train of discrete voltage or current pulses, often used in timing and control applications. In photonics and optics, terms such as laser pulsé or lumière pulsée refer to pulsed light sources used for time-resolved measurements or nonlinear effects. In biology and physiology, phrases like rythme pulsé or pulsations describe the rhythmic beating or arterial pulsations associated with heartbeat. In fluid dynamics or mechanical systems, débit pulsé or flux pulsé indicates flow that varies in bursts rather than remaining steady.

The English equivalent is pulsed or pulsed mode, and pulsés appears primarily in French-language technical writing. It is used to convey a non-continuous, burst-like behavior of a system or signal while remaining neutral in tone.
