Witryna21 lut 2013 · Apply the first filter. Apply the second filter. Continue until all filters are applied. The result shows how the combined filters convolve the unit impulse (provided the array is long enough that no data was lost), so the values in it are the coefficients for one filter that is the composition of the other filters. WitrynaCascading Two FIR Filters When you cascade two FIR filters together, the output of the first becomes the input to the second. The order does not matter. Either filter can be placed first, it makes no difference. The final result is the same even though the intermediate results are different.
