modulation

 

[ mɒdʒʊˈleɪʃən ]

Noun
Context #1 | Noun

electronic signal

Modulation is the process by which one signal (called the modulating signal) is used to modify another signal (called the carrier signal). This is commonly seen in communication systems where modulation allows the transmission of information over various media. The purpose of modulation is to encode the information onto the carrier wave, which can then be transmitted over long distances. Various forms of modulation exist, including amplitude modulation (AM) and frequency modulation (FM). Each type has its own applications and advantages based on the context in which it is used.

Synonyms

adjustment, alteration, variation

Examples of usage

  • The radio station uses frequency modulation to transmit its signal.
  • When dealing with sound waves, amplitude modulation can create variations in volume.
  • Television broadcasting relies on both AM and FM modulation techniques.
  • Understanding modulation is essential for designing effective communication systems.
Context #2 | Noun

musical term

In music, modulation refers to the process of changing from one key to another within a composition. This technique can create a variety of emotional effects and add interest to the music. Modulation may occur smoothly through stepwise motion or may be abrupt, creating tension and resolution. Composers often use modulation to significantly alter the feel of their piece, moving it from one tonal center to another. This can be a powerful tool in composition and arrangement.

Synonyms

key change, tonal shift, transposition

Examples of usage

  • The song features a modulation that shifts from C major to A minor.
  • In classical music, modulation can take the listener on an unexpected journey.
  • The transition between sections showcases the composer’s skill in modulation.
  • Many pop songs utilize modulation to build excitement before the final chorus.

Etymology

The term 'modulation' originates from the Latin word 'modulatio', which means 'a measure, or manner of arranging'. It is derived from the verb 'modulari', which translates to 'to measure'. Modulation has been used in various contexts throughout history, especially in the fields of music and communication. In music, modulation has been a fundamental technique since the Baroque period, allowing composers to explore different tonalities. In the 20th century, as technology advanced, the concept of modulation expanded into the field of electronic communications, where it became essential for transmitting data over various media. Today, modulation is crucial in both music composition and modern technology, showcasing its versatility as a concept.
