Hello everyone! I'm a complete beginner with LabVIEW and would like to ask the following question. For testing pieces, we apply a frequency sweep signal ranging from 330 kHz to approximately 360 kHz and observe the resulting signal. We observe a resonance curve, and if it's deformed (for example, on the oscilloscope, we see not just a single peak but several), it indicates an issue.
I have an NI USB 6351 card. Are there ways to compare these two signals in LabVIEW? For instance, can I take the signal from a conforming piece as a reference and compare it each time with the signal from the piece to be tested? Or are there other comparison methods in LabVIEW, whether based on signal shape, frequency content, or the similarity of the two signals?
