Eric,

Here, the data to delay and data to hilbert filter are entirely different. One 
is the
I path and the other one is the Q path, where in the gr.hilbert_fc case, it is 
the same
data input. hilbert_fc may be useful when the need to do hilbert trtansform 
occur early
in the chain, but in the method I implemented, it occurs later.

Is there a way, one can reliably do a "delay"? As I understand from Chuck's 
email quoting
earlier emails, there is no control over the buffering. I implemented the delay 
using a
filter, and it seem to do its job. Is there a better way to implement similar 
algorithms,
which occur frequently in communication systems?

Thanks
