modulèrent

Modulèrent is the past historic, third-person plural form of the French verb "moduler." The verb "moduler" in French translates to "to modulate" in English. This verb describes the action of changing, varying, or adjusting something, often in a controlled or regular way. The past historic, also known as the *passé simple*, is a past tense primarily used in written French, particularly in literature, historical accounts, and formal narratives. It denotes an action that occurred and was completed in the past. Therefore, "modulèrent" specifically indicates that a group of subjects modulated something at a specific point in the past.

The concept of modulation itself can apply to various fields. In music, it refers to the process of changing from one key to another. In telecommunications, it involves altering some property of a carrier wave, such as its amplitude, frequency, or phase, to transmit information. In a more general sense, it can describe the way sounds vary in pitch or intensity, or how a design or plan can be adapted or modified. When "modulèrent" is used, it implies that these actions of change or variation were performed by multiple entities in a completed past event. The context in which the word appears will clarify the precise nature of what was modulated and by whom.
