Before designing the filter, one must understand the relationship between the output voltage of the circuit and the frequency. For a series RLC circuit, how do the impedances of the circuit elements depend on the frequency? a. The impedance magnitudes do not depend on frequency.
b. Both impedance magnitudes decrease when the frequency increases.
c. The magnitude of the impedance of the capacitor decreases when the frequency increases; the magnitude of the impedance of the inductor increases when the frequency increases.
d. The magnitude of the impedance of the capacitor increases when the frequency increases; the magnitude of the impedance of the inductor decreases when the frequency increases.
