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