Consider the series RLC circuit shown in Fig. P14.49. When the output is the voltage across the resistor, we know this circuit is a band pass filter. When the output is the voltage across the series combination of the inductor and capacitor, we know this circuit is a band reject filter. This problem investigates the behavior of this circuit when the output is across the inductor.
a) Find the transfer function
when
is the voltage across the inductor.
b) Find the magnitude of the transfer function in part (a) for very low frequencies.
c) Find the magnitude of the transfer function in part (a) for very high frequencies.
d) Based on your answers in parts (b) and (c), what type of filter is this?
e) Suppose
Calculate the cutoff frequency of this filter, that is, the frequency at which the magnitude of the transfer function is ![]()
