🔍 Key Concepts

• Filter amplitude response in the passband vs. stopband • The meaning of maximally flat in filter design • Typical component requirements for different filter types (do they usually need only L or only C?)

💭 Think About

• Think about what the output vs. frequency curve of this filter looks like in the passband—does it prioritize flatness, sharp cutoff, or something else? • Which option describes a general shape of the response, and which ones talk about specific component choices? • Is a well-known named filter type usually defined by its component mix, or by its mathematical frequency response?

✅ Before You Answer

• Identify which choice describes a response characteristic (not hardware details). • Ask yourself which option is commonly associated with the phrase "maximally flat" in basic electronics or communications texts. • Verify whether well-known filter families (Butterworth, Chebyshev, etc.) are defined primarily by response shape rather than by specific inductor/capacitor-only constructions.
