Class: sigwin.gausswin

Generates Gaussian window

Syntax

win = generate(H)


Description

win = generate(H) returns the values of the Gaussian window object H as a double-precision column vector.

Examples

Gaussian Windows

Generate two Gaussian windows of length N = 64. Specify α values of 4 and 2. Show information about the window objects. Display the windows.

H4 = sigwin.gausswin(64,4);
H2 = sigwin.gausswin(64,2);

wvt = wvtool(H4,H2);
legend(wvt.CurrentAxes,'\alpha=4','\alpha=2')

The window with α = 4 has a wider mainlobe and less sidelobe energy.

Generate a Gaussian window with N = 16 and α = 3. Return the window values as a column vector. Show information about the window object. Display the window.

H = sigwin.gausswin(16,3);

win = generate(H)

win = 16×1
