moduladas

Moduladas is the feminine plural form of modulada, an adjective used in Spanish and Portuguese to describe things that have undergone modulation. The term can apply to signals, systems, or musical passages that have been altered by a modulation process, contrasting with items that remain unmodulated.

In electronics and communications, moduladas refer to signals that carry information by being modulated onto a carrier. Common modulation types include amplitude (AM), frequency (FM), and phase (PM). The modulated signal is transmitted over a channel and later demodulated at the receiver to recover the original information.

In music, moduladas describe passages or phrases that shift to a different key. Modulation can be achieved through pivot chords, chromatic sequences, or direct key changes, and is used to create contrast, tension, or a sense of arrival within a musical work.

Etymology: the word derives from the verb modular, via Latin roots associated with modulus, with the suffix -ada/-ado common to forming adjectives and past participles in Romance languages.
