Smoothing Windows

Applying a smoothing window to a signal is windowing. You can use windowing to complete the following analysis operations:

Define the duration of the observation.
Reduce spectral leakage.
Separate a small amplitude signal from a larger amplitude signal with frequencies very close to each other.
Design FIR filter coefficients.

The LabWindows/CVI Advanced Analysis Library includes the following windows functions:
