Modify Estimation Input Signals


When the frequency response estimation produces unexpected results, you can try
modifying the input signal properties in the ways described in “Troubleshooting
Frequency Response Estimation” on page 5-49.

Modify Sinestream Signal Using Linear Analysis Tool


Add Frequency Points to Sinestream Input Signal

This example shows how to add frequency points to an existing sinestream input signal
using the Linear Analysis Tool.

(^1) Create a sinestream input signal, in_sine1, as shown in “Create Sinestream Signals
Using Linear Analysis Tool” on page 5-39.
(^2) Double-click in_sine1 in the Linear Analysis Workspace area of the Linear Analysis
Tool.
The Edit sinestream dialog box opens.
3
In the Frequency content viewer, click in the Frequency content toolbar.
The Add frequencies dialog box opens.
(^4) Enter the frequency range of the points to be added.
(^5) Click OK to add the specified frequency points to in_sine1.
Delete Frequency Point from Sinestream Input Signal
This example shows how to delete frequency points from an existing sinestream input
signal using the Linear Analysis Tool.
