Specific Windows

Recall that the rectangular window transform is $\hbox{\sc Nyquist}(2\pi/M)$ , implying the rectangular window itself is $\hbox{\sc Cola}(M)$ , which is obvious.
The window transform for the Hamming family is $\hbox{\sc Nyquist}(4\pi/M)$ , implying that Hamming windows are $\hbox{\sc Cola}(M/2)$ , which we also knew.
The rectangular window transform is also $\hbox{\sc Nyquist}(K2\pi/M)$ for any integer $1\leq K\leq M/2$ , implying that all hop sizes given by for $K=1,2,\ldots,M/2$ are COLA.
Because its side lobes are the same width as the sinc side lobes, the Hamming window transform is also $\hbox{\sc Nyquist}(K2\pi/M)$ ,for any integer $2\leq K\leq M/2$ , implying hop sizes are good, for $K=2,\ldots,M/2$ . Thus, the available hop sizes for the Hamming window family include all of those for the rectangular window except one ( ).
