time delay calculation from two waveforms

[Ramesh VU]

Hi!

First of all My project is on non-contact velocity calculation. So I have designed two sensors and bandpass filter to filter the noisy waveform from the sensors to get nice sinusoidal waveforms. I have achieved that so far., but now i need to implement that to Labview (VI) as two analog inputs. and getting the time delay between first waveform and second wavefrom. As we know that velocity is Distance /time. I know the distance between two sensors but do not know how to calculte time delay using labview. As I am new to labview, can someone get me the block diagrams of two analog inputs, how to get them in labview using ADC.

PS: Can I design bandpass filter inside LabView. I would be very greatful if someone could help me out.

Thanking you alot guys

Ramesh,

Actually you dont need to 'design' things in LabVIEW more often, but simply use whatever is available inside.

Try searching Bandpass Filter in the Example Finder, you ll get.
