REVIEW PROBLEM FOR YOUR SPARE TIME, NOT TO BE TURNED IN
1.
Consider the circuit
This problem is to be solved using nodal analysis.
(a)
Draw the equivalent frequency domain circuit assuming
i
L
(0
!
)
=
2
Aand
v
C
1
(0
!
)
=
40
V.
(b)
Write three nodal equations for the circuit of part (a) only in terms of the voltages V
in
(s), V
out
(s),
I
L
(s), and of course the input and initial conditions.
SIMPLIFY EACH EQUATION.
(c)
Put equations in Matrix form.
(d)
Using Crammer’s rule or equivalent, find the transfer function
H
(
s
)
=
V
in
(
s
)
I
in
(
s
)
of the circuit.
(e)
Find the response of the circuit to
i
L
(0
!
)
=
2
.
(f)
Find the response of the circuit to
v
C
1
(0
!
)
=
40
and determine the zero input response.
(g)
Find the step response (the response due only to the step function with zero initial conditions) and
then the zerostate response of the circuit to
i
in
(
t
)
=
8
u
(
t
)
A.
(What principle should you use?)
(h)
Determine the complete response.
(i)
Find the zeroinput response if
i
L
(0
!
)
=
4
and
v
C
1
(0
!
)
=
20
.
