Steady-State Error

Using steady-state error analysis, determine e_ss, for a Type 0 Unit Step input.

Hint
Searching for "Steady-state error analysis" in the FE handbook used during the exam, you'll find the below table:
where $$T$$ denotes the type of system, i.e., type 0, type 1, etc.

The corresponding value associated with the "Unit Step" input and Type 0 is:
$$$e_{ss}=\frac{1}{(K_B+1)}$$$
$$$e_{ss}=\frac{1}{(K_B+1)}$$$
