w = nuttallwin(N) returns a Nuttall defined N-point, 4-term symmetric Blackman-Harris window in the column vector w. The window is minimum in the sense that its maximum sidelobes are minimized. The coefficients for this window differ from the Blackman-Harris window coefficients computed with blackmanharris and produce slightly lower sidelobes.w = nuttalwin(N,SFLAG) uses SFLAG window sampling. SFLAG can be 'symmetric' or 'periodic'. The default is 'symmetric'. You can find the equations defining the symmetric and periodic windows in Definitions.

w = nuttallwin(N)w = nuttalwin(N,SFLAG)

Nuttall and Blackman-Harris WindowsOpen This Example Compare 64-point Nuttall and Blackman-Harris windows. Plot them using wvtool. L = 64; w = blackmanharris(L); y = nuttallwin(L); wvtool(w,y) Compute the maximum difference between the two windows.max(abs(y-w)) ans = 0.0099
