Abstract :
This paper elucidates on the different types of filters used for DDC and DUC conversions. They constitute the most crucial functions in the implementation of SDR. The paper also further discusses filters from the point of view of its usage on different USRP platforms like USRPB100 and USRPN210 along with their respective analysis for interpolation and decimation operations. A comparative study of CIC, RRC and Half band filters on the basis of its computational requirements and magnitude responses is carried out.
