Description
Overview
This example shows how you can process a signal on your host computer using a Lowpass Filter Workspace Tool for Veristand.
Introduction
NI VeriStand is an open environment that can be customized in a variety of ways. NI VeriStand provides the user with a number of built-in workspace tools for signal monitoring and processing. Many applications, however, feature unique needs that can benefit from customized tools. The Lowpass Filter Workspace Tool allows the user to select a system definition channel, configure a lowpass filter for that channel and display the original and the filtered signal inside the workspace.
The example code comes with a Veristand project that you can use to test the functionality of the Lowpass Filter Workspace Tool. The project includes a model that generates a sine wave of a given frequency with a given noise amplitude and displays this signal on a workspace graph.
Steps to Implement or Execute Code
1. Run the SineWave.nivsproj Veristand project
2. In the Project Explorer window go to Tools » Workspace Tools » Custom Tool and select the Lowpass Filter Workspace Tool.vi
3. Select Aliases/Sinwave channel
