I do not want to sound rude or anything, but you are asking very basic questions on radio communications. You should read a textbook or go to an introductory class on that topic. You can find recommended documents on the suggested reading page[1]. Especially the "Digital Comms" section. Also a good idea would be to do an Ham Radio licensing course. These usually cover the most basic modulations and how it relates to real devices too.

All the prosperity and technological sophistication in the world is of no use without that foundation. -- Miss Matheson, The Diamond Age, Neil Stephenson _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
