@signalprocessing/windows v2.0.1

Signal Processing

The Signal Processing Windows module contains several windowing functions.

Install

npm install @signalprocessing/windows --save

Usage

Check external docs for the detailed explanation of windowing functions.

@signalprocessing/windows module can be both imported as commonJS module or ES module.

let windows = require("@signalprocessing/windows");

//Length of signal
let L = 1500;

• Hamming Window

let wm = windows.hamming(L);

//Default type of windowing function is symmetric. You may change it to periodic.

let wmP = windows.hamming(L, "periodic");

• Hann Window

let wh = windows.hann(L);

//Default type of windowing function is symmetric. You may change it to periodic.

let whP = windows.hann(L, "periodic");

• Flattop Window

let wf = windows.flattop(L);

• Rect Window

let wr = windows.rect(L);

• Barthann Window

let wb = windows.barthann(L);

• Bartlett Window

let wr = windows.bartlett(L);

• Blackman Window

let wbm = windows.blackman(L);

//Default type of windowing function is symmetric. You may change it to periodic.

let wbmP = windows.blackman(L, "periodic");

• Blackmanharris Window

let wbh = windows.blackmanharris(L);

//Default type of windowing function is symmetric. You may change it to periodic.

let wbhP = windows.blackmanharris(L, "periodic");

• Bohman Window

let wmn = windows.bohman(L);

This module is actively evolving. I am planning to add Tukey, Kaiser, Parzen, Taylor, Gauss, Triangular and Chebyshev windowing functions soon.
