I am trying to receive an on-off-keyed signal at 25kHz with USRP N210
The connection between N210 and Gnuradio works - I am able to visualize
it with the waterfall and the fft-sink.
I want to convert the signal to a time-discrete bitstream, where I have
1 for signal on and 0 for signal off. The switching between the two
states in the signal is very fast - only a few oscillations long.
How can I do this with Gnuradio?
