Efficiency Estimation of the Noise Digital Filtering Algorithms

The results of estimating the efficiency of digital filtration algorithms (median filtration, simple moving average and exponential moving average) by simulation under the influence of various types of noise (fluctuating, pulse and quasi-harmonic) are presented. As an estimation of efficiency, the attenuation coefficient as the ratio of the noise standard deviation at the input and output of the filters is used. The quantitative estimates of efficiency for various algorithms and their parameters, recommendations on the application of algorithms and the choice of their parameters are presented.
