How to sample an analog signal, simulated on labview and get the sample values.

[bhardoo]

My project involves this particular detail where i have to sample a simulated sine wave and get the samples and compare them so as to select a particular length for hanning window.Then it also requires me to experiment with the window size so as to get more efficient data out of the sampled signals. please help me with the sampling part and guide me as to how to perform a hanning window operation on the sampled signal. I have directly used the spectral analysis tool which involves getting a FFT spectrum by a default hanning window setting. But since i have to experiment with the window size and variations, guide me with the sampling part and applying a separate hanning window. Thank you.

What do you mean by i have to sample a simulated sine wave?

the sine generator will provide you with a waveform (or an array of values you can use), there are basic  vis to do all this, rigth click on the vi and select help to get detailed information.

Post your vi if you have trouble with details.

How much do you know about LabVIEW and signal theorie?

Thanks for the information, but what i am trying to achieve here is get samples at desired intervals, infact the sample values, so that i can compare them and fix a specific length for my hanning window through an alogrithm. so can u help me to convolute the signal and get the sampled data, so that i can exectue my alogrithm and get the desired result.

I'm not going to write your homework 😉

just open LabVIEW and start with the tutorial....
