Question 1
What is the formula for quality factor in L-section networks?
- Q = R_high/R_low
- Q = β(R_high/R_low - 1)
- Q = R_low/R_high
π‘ Hint: Focus on how quality is derived from resistance values.
Question 2
True or False: The stub length decreases with increasing susceptibility.
- True
- False
π‘ Hint: Think about the relationship between length and reactance.

Question 1
If a designer needs to calculate the quality factor for an RF amplifier with R_high=150Ξ© and R_low=75Ξ©, what steps do they take and what is the resulting Q?
π‘ Hint: Focus on simplifying the resistance ratio before applying the square root.
Question 2
A matching network uses a stub length where B=0.6 S and Y0=0.9 S with Ξ»=0.4 m. Calculate the stub length and discuss the implications of variations in reactance.
π‘ Hint: Visualize the stub impacts of lower vs higher reactance adjustments.
