Procedure (2), (3) and (4) are repeated 10 times to get sigma value.
relative to the ground level. So we specify random noise as follows.
Each of the output level at video output periods averaged over 200 ns period to get V (n) and V (n
The standard deviation of V is calculated after procedure (2) and (3) are repeated 30 times (30
