[Discuss-gnuradio] Question on DDC/USB interface

[Anastasopoulos Achilleas]

Guys,

How are the 4 complex streams out of the 4 DDCs multiplexed into the USB
port?
If the 4 ADCs sample at 64MSps, and each of the DDC's is downsampling by
N,
then there are 4 complex streams of 64/N MSps waiting to be transfered
through the USB port.
How do we control (if we can control) which of the 4 is transfered ?

Thanks
Achilleas
