Class: sigwin.nuttallwin
Package: sigwin

Generates Nuttall defined four-term Blackman-Harris window

Syntax

win = generate(H)

Description

win = generate(H) returns the values of the Nuttall defined four-term Blackman-Harris window object as a double-precision column vector.

Examples

expand all

Generate two Nuttall-defined four-term Blackman-Harris windows:

  • The first window has N = 64 and is symmetric.

  • The second window has N = 63 and is periodic.

Display the two windows.

Hs = sigwin.nuttallwin(64);
Hp = sigwin.nuttallwin(63);
Hp.SamplingFlag = 'periodic';

wvt = wvtool(Hs,Hp);
legend(wvt.CurrentAxes,'Symmetric','Periodic')

Generate a symmetric Nuttall-defined four-term Blackman-Harris window with N = 16. Return the window values as a column vector. Show information about the window object. Display the window.

H = sigwin.nuttallwin(16);

win = generate(H)
