 Part
1
 Consider
the
filter
circuit
shown
on
this
 diagram.

 Given
that
at
f1
=
12
kHz,
its
transfer
 function
magnitude
 
 H ( f1 ) = VOUT ( f1 ) 
=
0.8,

 VIN ( f1 ) VOUT ( f2 ) 
at
f2
=
50
kHz
(10
points).

 VIN ( f2 ) calculate
 H ( f2 ) = Your
answer:
______________________
 Also,
given
that
R
=
20
kΩ,
calculate
C
in
nF
(10
points).

 Your
answer:

 Part
2
 Consider
the
filter
circuit
shown
on
this
 diagram.

 Given
that
at
f3
=
30
kHz,
its
transfer
 function
magnitude
 
 H ( f3 ) = VOUT ( f3 ) 
=
0.4,

 VIN ( f3 ) VOUT ( f4 ) 
at
f4
=
350
kHz
(10
points).

 VIN ( f4 ) calculate
 H ( f4 ) = Your
answer:
______________________
 Also,
given
that
L
=
1.5
mH,
calculate
R
in
kΩ
(10
points).

 Your
answer:
