Michael Lee Posted August 14, 2021 Share Posted August 14, 2021 I'm currently trying digital ITC. I move around quickly from idea to idea like a road runner. ("meet meet!") The general idea is to receive 8 bits per second, with one parity bit. My field programmable gate array (FPGA) noise source yields 50 million random bits per second. Lets call the slow bits "group bits." 8 group bits per second. 8 group bits per "symbol". I decide on each group bit by summing 6,250,000 random bits. If its above the moving average, I assign a '1' , otherwise I assign a "0". Parity means that the number of 1s per second/symbol should be even. If it isnt, then that's a bad symbol. Goal would be to have no bad symbols. Symbols can be translated by 7-bit ASCII character set. Or we could reduce to a 5-bit letters only set. Either way, the first, very simple question is how good can spirits maintain parity? Random chance says there would be 50% symbols rejected. 3 Quote Link to comment Share on other sites More sharing options...
