I am suddenly a little bit confused about the difference between
usrp.source_s and usrp.source_c. Basically I have two questions:
Since the ADC only has 12 bits, does it mean the short integers
the computer have their last four bits as zeros? Or are their first four
digits are zero (the first bit should be the sign)?
Is anything interesting done when the short integers converted to
values? Or are they simply converted to a different type without
