Frequency shift to audible

[terry92054]

I'm processing ultrasonic (155KHz) signals that I'd like to shift to the audible spectrum and play through the PC speaker to allow the user to hear the spikes detected while testing. The nominal white noise is about 12mv peek to peek with spikes ranging from 20mv to 1 volt.

We currently do this in hardware but with the our new LabView monitor, we'd like to get rid of as much of the existing hardware and associated circuitry as possible.

Any suggestions on how to phase shift the 155KHz signal to the audible range and then play through the PC audio?

Thanks,

Terry

It seems to me that this question should better be posted to the LabView forum.

Yep. Moved to http://forums.ni.com/t5/LabVIEW/Frequency-shift-to-audible-in-real-time/td-p/1811128

Thank you for the suggestion.
