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 attachment has the be approved, and that might take a while. Can you type up the Identity?

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.
