Analysis of Frequency Characteristics of Simple Moving Average Digital Filtering System

The expressions of amplitude-frequency characteristics for different configurations of parameters of the digital filtering system (DFS) "Simple Moving Average" (SMA) are compared. The expressions of the phase response for the different configurations of parameters of the DFS SMA were compared and the corresponding phase shifts were calculated. The configurations of the parameters with the smallest phase shifts were determined and the optimal configuration of the parameters for the filtered value in the moving interval of the DFS SMA was ascertained.
