I am working on a problem where we measure some ripple over a huge constant. The problem is from electronics. You can think of as 100V DC always constant and we have a ripple of +/- couple mV over that 100V. Noise is constant. (i.e. 100V doesn't change and fairly constant)

Based on this our SNR calculation is -130dB, do you think it is possible to identify this mV signal out of this huge but constant noise?

Thanks, KD
