Abstract
DFT windows are applied by frequency domain convolution. Suitable windows, transformed to sums of delta functions, result in convolutions requiring the addition of few terms. These convolutions, applied to the DFT output, provide more accurate results and less computation if multiple windows need to be applied to the same data than does time domain windowing.
