SUMMARY
The DC gain of a second-order transfer function is determined by evaluating the transfer function at s=0. This involves substituting "0" for "s" in the transfer function equation. The discussion clarifies that taking the limit as s approaches infinity is not relevant for calculating DC gain. The correct approach is to directly substitute s=0 to obtain the DC gain value.
