How to Choose the Right DAQ Hardware for Your Measurement …

WebFor a 150 Hz sine wave the sampling theorem says that the sampling rate has to be at least slightly larger than 300 SPS. If you don’t mind processing large data sets, the sample rate can be set to 10-to-100 times the signal frequency, in this case 1500 SPS to 15,000 SPS. WebTo change the sample rate from 44.1 to 48 kHz, you have to determine a rational number (ratio of integers), P/Q, such that P/Q times the original sample rate, 44100, is equal to 48000 within some specified tolerance. To determine these factors, use rat. Input the ratio of the new sample rate, 48000, to the original sample rate, 44100. buddy holly fort myers

DAQ Assistant-Setting the Sample Rate and Samples to Read

WebLet's assume I have two cases of clean signal samples, namely y which has a sampling frequency of f s and z which has a sampling frequency of 2 f s. So we have (2) y n = y + n 1 (3) z n = z + n 2 This means that in y n I am using noise samples with the rate f s and in z n and I am using noise samples with the rate 2 f s. WebThis appears to have been made using LabView (Visual cues). It has an option to change the sample rate. My desired sample rate of 1Hz works when set through here.
