I am sorry that I may ask a question in the wrong place. But I do not know where to ask my question. Recently, I set a bounty of 150 points to my question A problem about SQNR, PCM, DPCM, and DM. After seven days, no one answer this question. And then, I lose the 150 points. Can the system return these 150 points to me? Thank you very much.
Note: I also want to apologize for my awful English writing ability because English is not my mother language.
