Median technique for noise reductions

Abstract

The problem of reducing the low-frequency drift, "flicker" and blasting noise, generated in the measuring tract in the process of forming a digital equivalent for a measured value has been considered. Methods are proposed to further reduce the noise composition in the results obtained. The minimization of noise components of type 1/f, 1/f2 and irregular blast noise in the output digital result is performed by means of digital filtering based on modified "Tukey53H3" algorithm. A one-stage algorithm for "SM9H3" is proposed with floating current fragmentation in signal processing. As an application, the results of the proposed signal processing methodology are shown and described.
