Specific Windows

• Recall that the rectangular window transform is , implying the rectangular window itself is , which is obvious.

• The window transform for the Hamming family is , implying that Hamming windows are , which we also knew.

• The rectangular window transform is also for any integer , implying that all hop sizes given by for are COLA.

• Because its side lobes are the same width as the sinc side lobes, the Hamming window transform is also ,for any integer , implying hop sizes are good, for . Thus, the available hop sizes for the Hamming window family include all of those for the rectangular window except one ( ).
