After FIR filter AXI stream datawidht converter is used again to get convert the interleaved samples of I and Q as single AXIS stream TDATA word. The processing is terminated by AXI stream DEVNULL that eats all. For visualization and data capture ILA Logic Analyzer IP cores are inserted. For test purposes the LO frequency was set to 134KHz (this is close to WSPR band where beacons are expected to be present in frequency band).

XADC Raw data, capturing 135MHz 135KHz signal from Zynqberry mic input.
