Weboptimum filter. The Wiener filter is probably the most common definition in use, and it relates to the configuration depicted in Figure 7.2. The kth sample of signal y, y k, consists of two components: the principal signal sk, and a noise component nk which is correlated with xk. The Wiener filter provides an optimal estimate of nk, known as nˆ k. WebAn example of Wiener filtering is given below. An ideal version of the cover of the Joshua Tree album by U2.
