Hi,
I would like to know if it is actually possible to do the above.
I'm currently working on wavelet based multiresolution analysis using LabVIEW Student Edition, which unfortunately doesn't have all the toolkits and Express VIs available for me to use. Attached is a VI I have created (Daub4.vi), and screencaps showing the results of the decimation.
What I'm trying to do is to decompose the signal by 8 levels, each time dividing the sampling rate by 2, done using decimate 1d array. However, in terms of keeping the signal length the same, I'm not too sure if I should actually manipulate the dt value or simply just use the waveform graph scaling factor to do the job. Some advice would be welcome.
Also, another problem I have is pretty weird:
I'm trying to extract a part of a very large ECG signal (1 second = 64 samples, sampling rate = 2048Hz, I have about 10 minutes of data), selecting from 40960 samples to 65536 samples. However, upon output, the waveform graph only shows up to 65535 samples instead of 65536. Is this supposed to be normal?
Thanks,
Derren
