I have a SNR of 10
I need to generate a signal and noise such that signal_power/noise_power will give this SNR value

Definitions quiz for you:
If you have a signal of one level, and a noise of a different level, then do you talk about a particular SNR ratio if:
  • the maximum of the absolute value of the signal is a particular ratio to the maximum of the absolute value of the noise ?
  • the mean of the signal is a particular ratio to the mean of the noise?
  • the average of the signal is a particular ratio to the average of the noise?
  • the median of the signal is a particular ratio to the median of the noise?
  • the power of the signal is a particular ratio to the power of the noise?
  • the peak-to-peak distance of the extremes of the signal has a particular ratio to the peak-to-peak distance of the extremes of the noise?
Or something else?
What, in other words, is the definition of SNR ?
