Question 1
What does insertion loss indicate?
- The level of reflection in the circuit
- The power loss when a filter is added
- The power gain in a circuit
💡 Hint: Think about the difference in signal power with a filter and without.
Question 2
True or False: Higher return loss indicates better impedance matching in filters.
- True
- False
💡 Hint: Consider what low return loss would tell you about the circuit.

Challenge Problems
Push your limits with challenges.
Question 1
A band-pass filter has a peak response at 100 MHz and a bandwidth of 20 MHz. Calculate the lower and upper cutoff frequencies.
💡 Hint: Think about how to find the range around the peak frequency based on the bandwidth.
Question 2
Given that a filter has a return loss of 30 dB, what percentage of the signal is reflected back?
💡 Hint: Consider the formula connection between return loss and reflected power.
