Hello Community, Recently I investigated Modulate Vector <https://wiki.gnuradio.org/index.php?title=Modulate_Vector> block and my observations are that this block has two filtering stages - firstly in the modulator (RRC filter) and secondly in itself (user providing the filter taps). The simple scheme of operation looks like in the below picture. So the question is: what is the purpose of the filter in modulate_vector_bc <https://github.com/gnuradio/gnuradio/blob/master/gr-digital/lib/modulate_vector.cc> function? Is this a bug or is there a reason for this? [image: Modulate vector question.png] -- BR,
