Window

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE WindowV2 MODULE INSTEAD.

This module applies different types of windows to the input. The input and output pin must have the same number of channels. The value startIndex specifies the starting of the range from where the window has to be applied. The index is zero based. and must lie in the range [0 blockSize-1]. The value endIndex specifies the ending of the range where the window has to be applied. The index is zero based. and must lie in the range [0 blockSize-1]. If startIndex and endIndex are outside of the allowable range, it is clipped to the ends of the buffers.
