Q.1 Find the DC gain of the following system.
Solution:
The DC gain at thesteady state when
∞can be found as
DC gain =
DC gain = 0.2
Q.2 Find the steady state and transient state gain of wash out circuit. A wash out
circuit is defined by the following transfer function.
F(s) = sT / (1+sT) where T is system time constant.
Solution:
Steady state gain can be found by applying Final Value Theorem whereas Transient
state gain can be found out by using Initial Value Theorem.
Steady state Gain=
Transient state Gain=
