Suppose we measure the noise in a resistor (with no applied voltage) and find that the noise voltage exceeds 10 μV 5% of the time.
We have reason to believe the noise is well modeled as a Gaussian random variable, and furthermore, we expect the noise to be positive and negative equally often so we take the parameter,σ2 , in the Gaussian PDF to be m =O .
Find the value of the parameter, . What units should be associated with in this case.
