In the article the analytical expressions for the calculation of non-recursive digital filter with relief amplitude-frequency characteristics. Non-recursive digital filter-tions (NTSF) have a linear phase response (PFC) and thus can be of any relief amplitude-frequency charac-teristic (AFC) in the band of pro-blowing. Due to this quality digital filters with a relief response may simul- Menno-filter noise from the signal and eliminate the amplitude-frequency signal distortions arising from the flatness of communication channels. In this paper anali-cal expressions for calculating the coefficients NTSF with relief response to four types: low pass filter (LPF), a high pass filter (HPF), band-pass filter (PF) and notch filter (RF). The basis of the formulas on the method of obtaining the smallest quad-Ratov (MNCs). The coefficients NTSF symmetric with respect to the central co-coefficient, which ensures linear phase. The resulting article formula for calculating the coefficients NTSF can be useful to developers of digital-signal processing howling.
