Closest peripheral aspect is transforming integrals according to Fourier, which extricates 1 cycle in f(x)=sin(x). A synchronization may take place in transient sine coefficient, where "Mag" and L2(R) column specify individual polar coordinates.

For example, the Fourier transform of Ly is. F[L(2)y] = L(2)˜y(k), where y(k) is the factor from L(2)y's distribution.
