Fourier

Target entity: Fourier
Context triple: [Jean-Baptiste Joseph Fourier, familyName, Fourier]

• A. Fourier analysis
  Fourier analysis is a mathematical method for decomposing functions or signals into sums of sinusoidal components, widely used in fields such as signal processing, physics, and engineering.
• B. Audion
  Audion is an early triode vacuum tube invented by Lee de Forest that enabled the amplification of electrical signals and was crucial to the development of radio and electronics.
• C. Riemann–Lebesgue lemma
  The Riemann–Lebesgue lemma is a fundamental result in Fourier analysis stating that the Fourier coefficients (or transform) of an integrable function vanish at infinity.
• D. Spectral
  Spectral is a 2016 military science fiction film that follows a special-ops team confronting ghostly entities in a war-torn Eastern European city.
• E. Syncopy
  Syncopy is a British film production company founded by director Christopher Nolan and producer Emma Thomas, known for backing many of Nolan’s major films.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
