[Discuss-gnuradio] Receiving On-Off-Keyed Signal

[Guido Schmitz]

Hello,

I am trying to receive an on-off-keyed signal at 25kHz with USRP N210
and Gnuradio.
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?

Kind regards,

Guido
