H Hamming Window. This window is unique in that the time domain shape
does not taper all the way to zero at the ends (see Figure 3--55). This makes
it a good choice if you wanted to process the real and imaginary parts of the
spectrum off line and inverse transform it back to the time domain. Because
the data does not taper to zero you could then remove the effect of the
window function from the result.
