| 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, 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, using a filter refinement 100 times, for a period of detailed analysis of only 400ms; refined by two filters 2000 times,abercrombie et fitch, for a detailed analysis of only 4s.
