The steady-state error for a Type 0 system for unit-step input is 0.2.

1.	The steady-state error for a Type 0 system for unit-step input is 0.2. In a certain instance, this error possibility was removed by the insertion of a unity gain block. Thereafter, a unit ramp was applied. The nature of the block and new steady-state error in this changed configuration will, respectively, be

B.	differentiator, 0.25
C.	integrator, 0.20
D.	differentiator, 0.20
Answer» B. differentiator, 0.25
