FILTERING OF A DISCRETE ELECTRIC FIELD SIGNAL USING THE PREVIOUS MOVING AVERAGE

Abstract

A filtering of a discrete signal of electric field intensity () in the frequency band from 76 MHz to 2686 MHz is proposed applying the previous moving average with n = 2. The database of temporal measurements of obtained was used. in the continuous monitoring of one day inside the ESPOCH using the NARDA SRM-3000 equipment. The vector of the mean values of the intensity of corresponding to each instant of time, is made up of 240 points because the measurements were obtained every 6 minutes, resulting in a signal of discrete intensity of . To achieve the correct smoothing (filtering) of, the previous moving average algorithm with n = 2 requires 30 passes or iterations. The result that was obtained was a smoother signal compared to the original signal, without the resulting signal losing its original shape.EEEE
