	Spotlight Story: Pass Data through a Window Many engineers understand the need to pass signals through an anti-alias filter prior to digitizing them. But they may neglect to apply a window function to their data prior to using a fast Fourier transform (FFT). The lack of a window can distort results and cause you to draw incorrect conclusions about test and experiment data. Full Story ADVERTISEMENT Learn How to Build your Measurement System on PXI PXI is the open, PC-based platform for test, measurement, and control.
