My partner and I are currently working on a project that involves finding a frequency
though the Fourier transform in LabView. Once the frequency is found, we would like
to send back a signal tone at that frequency through headphones. We are
having trouble making LabView accomplish this through our codes. Attached
is a zip file if you would need to see the block diagram, with our project
being White_Noise_Final.vi.
The test we are running is white noise that will be sent through an enclosed tube, when the tube opens up there is a plateau like effect in the spectrum (Example picture attached). The goal is to find the frequency of the plateau and resend that frequency. We have no way to exactly test this because we have no tubes available, but we believe the code we have will accomplish the goal. Is there a way to set a threshold to find this plateau? We attempted to use the Peaks.VI, but LabView did not agree. Is there something that we are missing?
Also, the requirement for the white noise is to be randomized between 1kHz and 10kHz, so the second signal should be in this range.
