Homework Help: Parseval's identity?

  1. Apr 14, 2007 #1
    1. The problem statement, all variables and given/known data
    Is this correct (in the document)?

    3. The attempt at a solution
    I have a feeling it is not.

    The first line
    [tex]\int \left|\phi(x)\right|^2 dx= \int \left|\psi(p)\right|^2 dp[/itex]
    is correct (and is the statement of Parseval's identity). The second line
    [tex]\int \left|\phi(x+1)\right|^2 dx= \int \left|\psi(p+1)\right|^2 dp[/itex]
    does NOT follow from the first.
