Thanks john , what i extracted from the information is that , in usrp the baseband is is centered with IF as close to zero .. right.Is that the IF conversion is same for all the frequencies and bands , and also how the ADC sampling process reacts to the different data rate baseband data ... Thanks , and i highly apologies for any mistaken information in my post . Thanks
