Re: [Discuss-gnuradio] synchronization between blocks

Hi Nemanja - Non-sync blocks -- ones that do not guarantee some number of output items given some number of input items -- cannot be assumed to have constant sample delay from input to output (or, in any other way; though they may have this property). This property is irrespective of what the b

Thank you Michael. Well, I think the problem comes from the block which is not of sync type. INputs to this block are demodulated signal and the very input signal, and the output are sybol values and signal value at the point of sampling. However I will try with logging and see what can I find. But

Hi all again, at the moment I thought that the problem was solved, but actually something strange is going on. I would only like to ask whether delay between two paths can roll out somehow (i don't know if this verb exists). The point is that at the beginig of the execution, it looks like the scri

Thank you Tom. The problem is that in the configuration that is attached delay must be arround 600 in order to allign two paths. Next I put a complex delay block in the second path just after the theottle (and removed the existing one) and it works fine with 330 (not perfectly alligned but ok). Is
