🔍 Key Concepts

• Shape of a bandpass filter frequency response (what frequencies are passed vs rejected) • Difference between low-pass, high-pass, bandpass, and band-stop/notch filters • Role of cutoff frequency (or frequencies) in defining the pass band

💭 Think About

• For each graph, ask: does it allow low frequencies only, high frequencies only, a middle range of frequencies, or all except a narrow range? • Which type of filter should show two cutoff frequencies, one at the lower edge and one at the upper edge of the passed band? • Compare the curve that passes a central band of frequencies to the one that rejects a central band of frequencies. How do their shapes differ?

✅ Before You Answer

• Identify which figures show one cutoff frequency and which show two cutoff frequencies • For each figure, decide whether low, mid, or high frequencies have the highest voltage across the load (those are the ones being passed) • Make sure the bandpass choice shows low output at very low and very high frequencies, with higher output in between
