hi,
the code I wrote is
#!/usr/bin/env python
from gnuradio import gr, gru, modulation_utils
from gnuradio import blks2
src_data = (0,1,1)
Bsrc = gr.vector_source_b(src_data,False)
Bsink = gr.vector_sink_b()
def build_graph():
fg = gr.top_block ()
Bmod = blks2.dbpsk_mod()
Bdemod = blks2.dbpsk_demod()
fg.connect(Bsrc, Bmod, Bdemod, Bsink)
return fg
if __name__ == '__main__':
fg = build_graph ()
fg.run()
print src_data
sink_data = Bsink.data()
print sink_data
regards,
Mehdi
