Bandpass filter based on complex analytical refinement of the complex modulation spectrum analysis of the algorithm
500, the maximum thinning ratio of up to 15O,[link widoczny dla zalogowanych], can still ensure the accuracy of the amplitude of the error in the 19 / 5 within the FIR filter using two multiple of the maximum fine of up to 2000 times; the CPU clocked at 200MHz on a microcomputer the operation,[link widoczny dla zalogowanych], using a filter refinement 100 times,[link widoczny dla zalogowanych], for a period of detailed analysis of only 400ms; refined by two filters 2000 times, for a detailed analysis of only 4s.
