Estimation of Temporal Correlation of Signal
The formula for the temporal corelation between a signal at time $k$ and the same signal at time $k+m$ is:
$$\rho_{k,k+m}=\frac{E((P_k-\overline P_k)(P_{k+m}-\overline P_{k+m}))}{\sqrt{ E((P_k-\overli …

Hammerstein integral equation with inverse of the solution
In signal processing theory I found this integral equation that I recognized to be of Hammerstein type:
$$u(t)-\int_{0}^{1}d\phi cos(\omega t+\phi)\frac{1}{u(\phi)}=0$$
Unfortunately the solution fun …
