WebJun 1, 1998 · The Hamming window has the lowest first side lobe level of all three types of windows, but after its first side lobe, its remaining side lobes decay slowly relative to … Haven't done this. But Hamming(idx) = 0.54 - 0.46 * cos(2PI * idx / (N-1)).So it, like the FT itself, is amenable to be run stepwise as idx sweeps acrosss the buffer. The line to change is complex delta = newest_data - oldest_data; - instead of taking the difference between the oldest and newest data values, the hamming function would need to be applied to both values prior to taking the ...
