Modulál

Modulál is a Hungarian verb meaning to modulate. In technical contexts it denotes the act of varying a property of a signal or system over time in a controlled way. The term is widely used across electronics, telecommunications, acoustics, and music theory, reflecting a general concept of adjusting a carrier or tone to convey information or to transition between states. The word is a direct loan from the English verb modulate, and the related noun moduláció is used for modulation.

In electronics and communications, modulál refers to changing one parameter of a carrier signal—commonly amplitude, frequency, or phase—according to a modulating signal. The resulting process is called modulation and yields variants such as amplitude modulation, frequency modulation, and phase modulation. In music, modulál can mean changing the key or tonal center within a composition, often as a transition to a new section or a broader harmonic shift.

Conjugation and related forms in Hungarian include modulált (past tense) and moduláló (present participle or relative descriptor). The term is part of a broader linguistic and technical family that includes moduláció for modulation. In practical usage, modulál appears in scientific, engineering, and educational texts to describe how a signal or musical structure is adjusted over time.
