3D Waterfall Plot to view Noise over time

[Che_T.]

Overview

This example shows how to use the 3D Waterfall plot.

Description

In this VI, two sine waves are generated -- 1 with periodic random noise, 1 clean sine wave.  20% of the time, we see the noisy sine wave, and 80% of the time, it's a clean one.  We take the FFT of the signal to determine which frequencies we see our noise on.

Requirements

• LabVIEW 2012 Full Development System (or compatible)

Steps to Implement or Execute Code

1. Run the VI and the 3D Waterfall control will display the surface of the FFT of the signal.
2. The Graphs and Array on the right show the signals and FFT to help understanding the VI.
