Repeating the same kind of filter seems less necessary, but given that we can support it at no cost I don’t see why we should try to prevent it. For the array filter, I would say that having two in a filter chain is not redundant if there is a filter in between the two that changes the meaning of data, i.e., an array-to-array function like FFT. Looking at a region of interest, Fourier-transform, then look at a specific part of the spectrum. Don't know if that is a valid use case, though, and there is no FFT filter. Two array filters in a row seem redundant. Cheers, ~Ralph
