AP2.4 Consider a DC amplifier given by

Co, the output resistance and capacitance, respectively.
The DC amplifier is illustrated in Table 2.4. (a)
Determine the response of the system to a unit step V1 (s) = 1/s.

(b) As t → ∞, what value does the step response determined in part

(a) approach? This is known as the steady-state response.

(c) Describe how you would select the system parameters Ro and Co to increase the speed of response of the system to a step input.

V ($) ka V(s) RoCos+1' where V2 (s) is the output voltage and V(s) is the input voltage. The system parameters are R, and
