Using the DSP Blockset (DSP Blockset)

DSP Blockset

Working with Windows

Windowing is a common technique used in digital signal processing, and is supported in the DSP Blockset library with the Window Function block in the Signal Operations library.

The Window Function block provides three modes of operation:

Generate and output the coefficients of a selected window.
Apply an existing window to the input signal.
Generate the coefficients of a selected window and apply the window to the input signal. Output both the window coefficients and the windowed signal.

The parameters in the block dialog box (above) change to reflect the options available for the particular mode of operation and the selected window. Note that for any combination of these settings, there are always some inactive parameters.
