I should have seen that answere coming. I am trying to get the book, no
luck so far.
The default values dont seem to work.
What should the data going in and out of the gr.clock_recovery_mm_ff look
like?
I see that in gmsk2.py you remove DC offset, should the signal be varying
+/-Vpeak equally?
Any requirements that the signal should be over sampled?
Is the output basically resampled at the data clock rate so that each
output point represent a bit?
