Shuning Liu 0 Report post Posted December 5 Hi, I have a problem about re-sampling signals. I have two sampling signals with different sampling rates. I want to add these two signals together into one output signal. But when I just use "add" buffer, an error occurs and it tells me that two signals with different time intervals can't be added. So I tried to use "Re-sample" block to re-sample Arduino signals. But it seems that this function can't re-sample signals with smaller time interval, which means it can't add extra samples when sampling. Can anybody help me solve this problem? Or do you have any ideas that can help me add these two signals? My file is below. Many thanks! analog input arduino+sound card (add signal).vi Share this post Link to post Share on other sites
