autocorrelation function problem

[malik123]

hi

i am using Labview 2009 at school but at home i have Labview8.6, i build a VI that contain a sine wave and noise and want to use autocorrelation function. 

but after adding noise it to the signal the result is not clear i mean not a proper cosine wave, am i missing some thing? please correct me. and if possible then save my VI to 8.6 because i cant open it on my PC as i have 8.6 on my PC 

Thanks

Your sample frequency is 10.000 Hz while the sine frequency is 1.000 Hz. This means you have 10 samples per period. If you make this factor bigger you will get a nicer sine wave.

Thanks for the answer ton 

you mean that i have to increase the  sampling frequency of sine signal?
