Operating System:XP SP3

Dear Sir/Madam,

I captured tach signals whose wave form is sinusoidal one.
Amplitufe is 30 mV or so and speed is keep on changing.
It was saved into ASCII format.

Is there any way to read the speed or count the signal frequewncy from the raw tach data on ORIGIN?

If yes, please let me know how to do it.
It will be greatly appreciated if you give me any clue to that.

Best Regards,


Jeongsoo

You need OriginPro and use Short-Time Fourier Transform (STFT)

See
