Indeed Thomas you are right: one would want much better signal to noise ratios in a system controlling air bags and anti-lock brakes and CDMA cellphones and so on. My comment was not about the magnitude of the S/N ratio, but the SIGN! Less than zero dB! Do you understand what this means? I'm sure there are some folks lurking this thread well versed in plucking wireless signals from the air who can explain it for you. Think about what it means to have a S/N ratio less than zero dB and maybe remark about the merits of a purported control system exhibiting such characteristics. I can save you some time: one proper term for such a system might be 'noise following'... Hey... maybe that was my point after all? John
