WebCorrelation Theorem for the DTFT. We define the correlation of discrete-time signals and by. The correlation theorem for DTFTs is then. Proof: where the last step follows from … 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 originates from a 1799 theorem about series by Marc-Antoine Parseval, which was later applied to the Fourier series. It is also known as Rayleigh's energy theorem, or Rayleigh's identity, after John William Strutt, Lord Rayleigh. Web4.3.10 Parseval’s and Plancherel’s Theorems : ...
