🔍 Key Concepts

• Transmission line stubs and how shorted stubs behave at different fractions of a wavelength • Relationship between harmonics (especially even harmonics) and standing wave patterns on a line • How quarter-wave and half-wave sections transform impedance on a transmission line

💭 Think About

• Think about what impedance a shorted line presents at its input when its physical length is 1/4, 1/2, or other fractions of a wavelength • Ask yourself: at which line length will a short circuit at the end look like a high impedance (open circuit) at the connection point? • Consider which stub length would create a condition that absorbs even harmonics while not significantly affecting the fundamental frequency

✅ Before You Answer

• Review how a short-circuited line behaves at lengths of λ/4 and λ/2 in terms of impedance transformation • Confirm which line length makes a short appear as an open circuit at the feed point • Verify which of the given options corresponds to that specific fraction of a wavelength behavior used to filter out even harmonics
