Thanks for the very detailed explanation, Marcus. I think quite a bit of my trouble here is relating GNU Radio terminology to hazily-remembered signal processing courses I took fifteen years ago and haven't used a whole lot since.
So, using a rational resampler at 4x decimation, with no separate aliasing filter and the 'Filter taps' parameter left empty will mean that there will be aliasing in the resulting down-sampled data. Have I understood you right? I need to provide filter taps to get an anti-aliasing filter as part of the resampler block?
Thanks again,
Tom
