Dear all, I have some questions regarding the DDC implementation (ddc_chain.v, usrp2):
1) Why do we need two half-band filters (one large and one small) after the CIC? What is their purpose? Can’t we use just one half-band? 2) What is the purpose of the scale factor multiplication after hb2? What does it compensate for? How do we decide its value? Thanks, Francesco _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
