Signal Processing Onramp (Preprocessing Signals -- Extract Interesting Regions)

You can extract the data from the surface waves by removing extra points before and after. You can find the Extract Signals option in the Region of Interest section.

TASK

Extract the selected region from the harp, pax, and wanc signals. Make sure that the extracted signals are named harp_ROI, pax_ROI, and wanc_ROI respectively and display them.

Error I'm getting:

First extract all three signals.then you have to export all this three signals(harp_ROI, pax_ROI, and wanc_ROI) to wrokspace browser.

Exit preprocessing. Then click on the 'Display' tab and look for the Extract Signals option in the ribbon.

Click 'Hint' underneath the task description if you are having trouble finding it.
