It is also known as Rayleigh's energy theorem, or Rayleigh's identity, after John William Strutt, Lord Rayleigh. Although the term "Parseval's theorem" is often used to describe the unitarity of any Fourier transform, especially in physics, the most general form of this property is more properly called the … See more In mathematics, Parseval's theorem usually refers to the result that the Fourier transform is unitary; loosely, that the sum (or integral) of the square of a function is equal to the sum (or integral) of the square of its transform. It … See more In electrical engineering, Parseval's theorem is often written as: where See more • Parseval's Theorem on Mathworld See more Suppose that $${\displaystyle A(x)}$$ and $${\displaystyle B(x)}$$ are two complex-valued functions on $${\displaystyle \mathbb {R} }$$ of period $${\displaystyle 2\pi }$$ that … See more Parseval's theorem is closely related to other mathematical results involving unitary transformations: • Parseval's identity • Plancherel's theorem • Wiener–Khinchin theorem See more WebUTokyo Repositoryは本学で生産されたさまざまな学術成果を電子的形態で集中的に蓄積・保存し、世界に発信することを目的としたインターネット上の発信拠点です。 The …
