[Discuss-gnuradio] slicer question

[George Barrinuevo]

I am trying to get the gr.binary_slicer_fb() to work,
but it gives me an error.  The _fb means float to
binary, correct?  Are there any arguments to
gr.binary_slizer_fb()?  Can someone tell me what is
wrong?

----------
   complex_to_float = gr.complex_to_float ()
   slicer = gr.binary_slicer_fb()
   dst_file = gr.file_sink(gr.sizeof_float,
"out_file2.txt")
   self.connect (ddc, complex_to_float, slicer,
dst_file)
----------
