Blackman-Harris Window Family

The *Blackman-Harris* (BH) window family is a straightforward
generalization of the Hamming family introduced in
§3.2. Recall from that discussion that the
generalized Hamming family was constructed using a summation of three
shifted and scaled aliased-sinc-functions (shown in Fig.3.8). The
Blackman-Harris family is obtained by adding still more shifted sinc
functions:

where , and is the length zero-phase rectangular window (nonzero for ). The corresponding window transform is given by

(4.27) |

where denotes the rectangular-window transform, and as usual.

Note that for , we obtain the rectangular window, and for , the BH family specializes to the generalized Hamming family.
