[Discuss-gnuradio] usrp.source_s and usrp.source_c

Hi, Guys

I am suddenly a little bit confused about the difference between usrp.source_s and usrp.source_c. Basically I have two questions:

1. Since the ADC only has 12 bits, does it mean the short integers entering the computer have their last four bits as zeros? Or are their first four digits are zero (the first bit should be the sign)?

2. Is anything interesting done when the short integers converted to float values? Or are they simply converted to a different type without changing the values?

Thank you~
