You're absolutely right, Marcus. I also think it'd be quite difficult to find a truly general-purpose solution to that. Knowing George's field of interested, I was assuming something like a simple energy detector. I think even this simple example shows the difficulties quite clearly. -Andre _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
