G. Tuccari, INAF - Istituto di Radioastronomia, Noto - Italy
The project of the third version for DBBC backend system implementation is presented. This system is able to fully implement in digital the functionalities required by a complete VLBI2010 backend, including the sky frequency conversion in the entire range 2-14 GHz, so avoiding any need of an analogue down-conversion to be used as preprocessor of a polyphase digital filter bank. The architecture and adopted methods are described.
