sigwin.bartlett class - Package: sigwin

Construct Bartlett window object

Description

sigwin.bartlett creates a handle to a Bartlett window object for use in spectral analysis and filtering by the window method. Object methods enable workspace import and ASCII file export of the window values.

For N even, the following equation defines the Bartlett window:

For N odd, the equation for the Bartlett window is:

Construction

H = sigwin.bartlett returns a Bartlett window object H of length 64.

H = sigwin.bartlett(Length) returns a Bartlett window object H of length Length. Length must be a positive integer. Entering a positive noninteger value for Length rounds the length to the nearest integer. Entering a 1 for Length results in a window with a single value of 1.

Properties

Length

Bartlett window length. The length requires a positive integer. Entering a positive noninteger value for Length rounds the length to the nearest integer. Entering a 1 for Length results in a window with a single value of 1.

Methods

generate	Generates Bartlett window
info	Display information about Bartlett window object
winwrite	Save Bartlett window object values in ASCII file

Copy Semantics

Handle. To learn how this affects your use of the class, see Copying Objects in the MATLAB Programming Fundamentals documentation.

Examples

Create default length N=64 Bartlett window:

H = sigwin.bartlett;
wvtool(H); 

Generate length N=128 Bartlett window, return values, and write ASCII file with window values:

H = sigwin.bartlett(128);
% Return window with generate
win = generate(H);
% Write ASCII file in current directory
% with window values
winwrite(H,'bartlett_128')
