Overview
This module applies different types of windowing functions to the input.
Discussion
This module applies different types of windows to the input. The input and output pin must have the same attributes. This module will operate only on non-complex float samples.
Certain window types take optional arguments (opt1 and opt2). To see what the optional input arguments are, see the Matlab help for the individual windows, for example, KAISER or CHEBWIN.
