A bandpass filter is shown in Fig. P4–8.
(a) Find the mathematical expression for the transfer function of this filter, H(f ) = V2(f )/V1(f ), as a function of R, L, and C. Sketch the magnitude transfer function |H(f)|.
(b) Find the expression for the equivalent low-pass filter transfer function, and sketch the corresponding low-pass magnitude transfer function.
