The article is devoted to the research of the method of digital filtering of a mixture of signals at ultra-low frequencies. A mathematical model of the system has been developed that includes an adequate signal model that really brings the result. The type of filter and the window function that is included in it were selected, and an algorithm for digital filtering of the signal mixture was developed that allows the most accurate selection of the received signal parameters. The obtained research results confirmed the efficiency of the mathematical model and the filtering algorithm of the signal mixture, and also proved their practicality in use.
