[Discuss-gnuradio] Purpose of extra two bits sent to FX2 chip with data samples

2009-01-31 Thread Paul Creekmore
The FPGA on USRP1 sends an extra two bits of data with each 16-bit word (to the FX2 chip). If I'm not mistaken, the first bit is set when accompanying a sample from rx channel 0, and the second bit is set when accompanying an inphase (as opposed to quadrature) sample (presumably from channels
