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 aliased sinc functions (shown in Fig.3.2). The Blackman-Harris family is obtained by adding still more shifted sinc functions:
