Reception of samples at other frequency of digitization

[tumanovalex]

Hi!

There are samples of a sinusoid frequency of 500 Hz received at frequency of digitization Fs = 10 кгц (I receive by means of Sine Waveform). It is necessary for me, I use these samples , to receive values of samples at frequency of digitization Fs-dFs distinguishing from 10 кгц on some value (dFs) .I need to receive values of these samples by means of function Sinc, however the sinusoid received as a result differs from a sinusoid received at the same frequency of digitization (Fs-dFs) by means of Sine Waveform. Help me, please!

Hi Alex,

I see that you have posted a VI here to take a look at, but I am very unclear what your goal is from the information you have provided.  I understand you might not be receiving your desired outputs, but it will be very difficult for me to advise any changes in logic, without a better understanding of what you need.  Please provide everything you can to clarify what it is you are working with and what it is that you need from this application.  In the meantime, I would suggest trying to search from within some of the resources we have at ni.com/support.  Here you might be able to find one of our toolkits will provide this exact functionality.  Thanks.

At me very bad English, and a translation system yields bad results. Look, please, my program and all of you it becomes clear.

I edit my Vi for you, i write my comment in Vi. Thanks for the help!

hi,

I tryied to multyply at Fs by 1*pi instead of 2*pi, and then graph1 was like graph2.

best regards,
