Remember that while the ADCs are 12 bits, we carry 16+ bits of precision throughout the signal processing.
Matt,How do you get 16 bits of precision from a 12 bit ADC? What does 16+ mean? I'm looking at the shorts coming from the USRP and I'm seeing values in the range [-3296 3264] which implies more than 12 bits... curious.
FYI, we supposedly tuned our front end to saturate the ADC 1% of the time. Thanks, Chris
