This node multiplies the input rows with a window function to prevent spectral leakage in subsequent FFT. You might want to use this node together with the Fast Fourier Transform (FFT) Node.

This node is part of the DSP Extensions provided by AI.Associates GmbH, Germany. For more information please refer to https://ai.associates/knime or write an email to knime@ai.associates.
