Maybe I should have provided some more context:
I have very little control of the sampling rates and the pre-filtering (without some hardware changes to our readout electronics). The electronics have been designed to provide a waveform trace with these two different sampling frequencies. Our...
Yes, thanks for clearing that up; I now agree that all the aliasing in my slower-sampled data will give me useless Fourier transform information.
Thank you also for your suggestion re:low pass filtering, and I'd like to pursue this further. I suppose the steps to take would be to (1) put the...
Hi All,
I have a problem I've been thinking about for a while, but I haven't come up with a really satisfactory solution:
I want to do a discrete Fourier transform on data that has been sampled at 2 different sampling frequencies. I've attached a picture of what my data will look like...
