Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the formula for calculating voltage gain?

  • A_V = V_1 / V_2
  • A_V = V_2 / V_1
  • A_V = V_1 + V_2

πŸ’‘ Hint: Remember, it's output divided by input.

Question 2

True or False: A high input impedance is desirable in amplifiers.

  • True
  • False

πŸ’‘ Hint: Think about how signals enter the amplifier.

Challenge Problems

Push your limits with challenges.

Question 1

An amplifier has Z_{11} = 50Ξ©, Z_{12} = 25Ξ©, Z_{21} = 25Ξ©, Z_{22} = 75Ξ©, and Z_L = 100Ξ©. Calculate the input impedance Z_{in}.

πŸ’‘ Hint: Use the input impedance formula carefully and substitute the terms.

Question 2

If an amplifier's output impedance is Z_{out} = 30Ξ©, and it is coupled with a load resistor of 15Ξ©, discuss the impact on the output signal.

πŸ’‘ Hint: Consider how output impedance affects load interactions.
