Hi Tom,
Thanks for the prompt and helpful advice. I have now tried changing the seeds
on the two noise blocks to different negative values (-42 and -99), and it does
indeed appear to have resolved the problem. Or having one positive (+42) and
one negative (-99) also solved the problem.
I think you are right that this should be in the documentation. At the moment
the documentation is very misleading, in that a) The default seed in the GRC
block is 42, which is a great number, but unfortunately is positive, and b) the
documentation when you click on the block says "noise_source_c(gr_noise_type_t
type, float ampl, long seed = 3021) -> gr_noise_source_c_sptr", which again
hints at a positive seed (i.e. of +3021).
Cheers, and thanks again.
Damian.
