🔍 Key Concepts

• Role of inductance (L) and capacitance (C) in setting a circuit’s resonant frequency • Difference between center (resonant) frequency of a band-pass/band-stop filter and how sharp or damped the filter is • How input voltage magnitude and load resistance affect amplitude and bandwidth rather than the actual resonant frequency

💭 Think About

• Look at each filter in the illustration: what elements are always present in the selective (frequency-choosing) part of the circuit? • Recall the basic formula for the resonant frequency of an LC circuit—what components appear in that formula, and which do not? • Think about what changing the load resistance or input voltage would do: would it move the pass/stop frequency, or just change how strong or narrow the response is?

✅ Before You Answer

• Be clear on what band pass / band stop frequency means: it’s the frequency location, not the output level or bandwidth. • Verify which answer choices involve the components in the standard resonance formula $f_0 = \frac{1}{2\pi\sqrt{LC}}$ . • Confirm that input voltage magnitude and total load resistance mainly affect gain and damping (Q), not the actual center frequency of the filter.
