Neutronic signal conditioning using Shannon functions

In order to guarantee the stability of BWR-type reactors, engineers have developed different methods of analysis. A new method based on generalized discrete Shannon functions to signal conditioning is being introduced in this paper. Shannon functions are the natural bridge between the Fourier transform method and the filter techniques family. This is an elegant way to clean and filter signal in some desired band of frequencies. As an example of application, we will remove some noise from a signal in a specific frequency band. We focus our attention in oscillating signals. First of all, we test the behavior of the algorithm on analytic signals and afterwards check it with real neutronic ones. The obtained results confirm that this is a very powerful and robust method to conditioning the signal and analyze them
