The filter may be used for cascade realization of digital filters in radio-electronics. It assists to simultaneously create low frequency, high frequency and phasing units without limiting cycles and reduced sensitivity to the multiplying coefficient. The filter consists of first, second, third, fourth and fifth summators (1,2,3,6,7), time-delaying unit (4), multiplier (5) and a strike-off device (8). The inlet to the filter is connected to first, second and fourth summators (1,2 and 6). The outlet of the third summator (3) is a low frequency filter, while the outlet of the fourth summator (6) - the outlet for the phasing unit of the first tier. The outlet of the strike-off device (8) is the high frequency exit of the filter.
