tukeywin

Compute a Tukey window

Syntax

• w = tukeywin(n,)
  

Description

w = tukeywin(n,r) returns an n-point, Tukey window in column vector w. Tukey windows are cosine-tapered windows. is the ratio of taper to constant sections and is between 0 and 1. is a rectwin window and is a hann window.

Examples

Compute 128-point Tukey windows with five different tapers and display the results using WVTool:

• N=128;
  t0=tukeywin(N,0);                 %Equivalent to rectangular window
  t25=tukeywin(N,0.25);
  t5=tukeywin(N,0.5);
  t75=tukeywin(N,0.75);
  t1=tukeywin(N,1);                 %Equivalent to Hann window
  wvtool(t0,t25,t5,t75,t1)
  
  
  

Algorithm

The equation for computing the coefficients of a Tukey window is
