Abstract :
Causality of tabulated data is detected by checking for Hilbert-consistency between data´s real and imaginary parts. This consistency can be robustly checked if the generalized Hilbert transform is used. Existing algorithms evaluate an integral in this transform numerically. In this paper, a new algorithm for checking causality that involves only analytical integration is presented.
