An alternative to the prototype band pass filter illustrated in Fig. P15.14 is to make
 ![]()
a) What is the value of C in the prototype filter circuit?
b) What is the transfer function of the prototype filter?
c) Use the alternative prototype circuit just described to design a passive band pass filter that has a quality factor of 16, a center frequency of 25 kras/s and an impedance of 10 kΩ at resonance.
d) Draw a diagram of the scaled filter and label all the components.
e) Use the results obtained in Problem 15.14 to write the transfer function of the scaled circuit.
Problem 15.14
The voltage transfer function of the prototype band pass filter shown in Fig. P15.14 is

Show that if the circuit is scaled in both magnitude and frequency, the scaled transfer function is
