Q5: (Transfer function 25 pts):
(a) Explain qualitatively if the active filter below is a low-pass of high-pass filter? Derive the
analytical expression for the transfer function T(s) =Vo/Voft Vo/V of the filter?
V
RIC
R2
??
(b) Depending on your answer to part (a), put the transfer function in the form of a low pass
filter, i.e.,
T(s) = K/[1+]
\frac{s}{\omega_0}
]
or in the form of a high pass filter, i.e.,
\omega_0
K
T(s) = \frac{s}{[s + \omega_0]}
Derive analytical expressions for the parameter K and 3dB break angular frequency of the filter
in terms of a combination of the capacitance C and the resistors R, and R2.
(c) Select values of the capacitance C and the resistors R, and R? so that K = 0.5 and the 3dB
angular frequency wo is Ikrad/s.
