Windowing function in Fourier Transform is an attempt to adjust the beginning and end of our signal feeds to FFT is … NettetDate windowing is a workaround to the inability of many legacy systems to deal with four-digit years. The workaround consists of having the systems still keep two-digit years and resolving ambiguity by defining a 100-year window that contains all years in the data.
