**Interpretation:**

Signal-to-noise ratio for a DC current shown in a figure should be estimated.

**Concept introduction:**

The mean current is given as

For a DC current, the signal-to-noise ratio is defined as follows,

If the deviation from the mean value is assumed to be random, the standard deviation of a DC current can be measured as follows,
