Abstract

The paper presents a filtering and enhancing technique for the elimination of the noise and instrumental errors from the experimental data. The technique is based on the least square method and the finite difference representation for the constrained equations. Previously developed filtering technique [1] has been modified to make if effective at the boundaries of the analyzed area. The condition of smoothness of the analyzed quantities is introduced at the boundaries. A simple relation for the matrix filter was obtained taking into account the additional smoothness constraints. 1. Introduction Very often , while analyzing the data from measurements , we know that they should be smooth. Applying the previo
