FIELD: real-time digital signal processing for miscellaneous devices and systems. SUBSTANCE: filter has series-connected digital Fourier transform unit, multiplying unit, spectral resolution raising unit, as well as inverse digital Fourier transform unit; connected to second input of multiplying unit is output of storage unit. This requires approximately twice as low hardware cost required for filtering which is equivalent to actually twice as high speed of device. EFFECT: enlarged functional capabilities; improved speed of digital filter. 3 dwgo
