lock-in

[wouince]

Is it possible to create a lock-in in Labview.

I ve tryied to download the example but I understand nothing.

Please help me and send me an easy program

My signal is 0.01 mV amplitude and the noise is 0.2 mV amplitude and it s 30 kHz frequency.

Could you send me just a simulation, I ve worked on Labview 7.1

this is my signal

Have a look at, for example, http://sine.ni.com/apps/utf8/niepd_web_display.display_epd4?p_guid=042319214C65627AE0440003BA7CCD71

(found by doing a search for lock-in amplifier example on ni.com)

I saw this fonction and I try to work whith it but i understand nothing

If you understand it could send me just a simulation whith a signal+big noise input and only the signal output.

Looked at your posting and it does not contain any data.

I think you need more basic understanding of Labview before attacking something like lock-in processing. I really think you need to start with basic Labview tutorials. Or you can pay someone to do this for you.

Labview is a difficult program to get started with and people here will help with the tricky bits. But not doing the whole thing for you.
