🔍 Key Concepts

• Filter passband characteristics (what happens to the amplitude in the passband) • Difference between Butterworth (maximally flat), Chebyshev, and constant-k / m-derived filters • Meaning of ripple in a filter’s frequency response

💭 Think About

• Compare which option describes something that happens specifically in the passband amplitude response of a Chebyshev filter • Ask yourself: which choice actually mentions a non-flat response characteristic in the passband? • Think about which option is describing a general network property rather than a specific Chebyshev response shape

✅ Before You Answer

• Identify which choice corresponds to maximally flat response and recall that this is associated with Butterworth, not Chebyshev • Check which option explicitly mentions ripple in the passband and consider if that matches what you know about Chebyshev filters • Eliminate any answer that talks only about component types (like inductors only) instead of the frequency response shape
