Interchange the Rs and Cs in the circuit in 1, that is- replace R1 with C1, R2 with C2, and vice versa.

a) Analyze the circuit qualitatively and predict the type of filler implemented by the circuit.
b) Verify the conclusion reached in (a) by deriving the transfer function Vo /Vi. Write the transfer function in a form that makes it compatible with the entries in Table 15.1.
c) How many free choiccs are there in the selection of the circuit components?
d) Find R1and R2 as functions of bo, b1, C1, and C2.
e) Are there any restrictions on C1 and C2?
f) Assume the circuit is used in a third-order Bulterworth filler of the type found in (a). Specify the prototype values of R1 and R2 in the second-order section of the filter if C1 = C2 = 1 F.
