Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for the gain of a non-inverting amplifier?
- Av = -Rf/Rin
- Av = 1 + Rf/Rin
- Av = R2/R1
π‘ Hint: Focus on how this amplifier interacts with the input signal.
Question 2
True or False: Positive feedback is commonly used in linear applications.
- True
- False
π‘ Hint: Consider why one feedback type might stabilize a signal.

Question 1
Design an inverting amplifier with a gain of -50 using a 10 kΞ© resistor for Rβ. What size resistor do you need for Rβ?
π‘ Hint: Apply the gain equation we've discussed.
Question 2
Create a differential amplifier circuit with Rβ = 5 kΞ©, Rβ = 15 kΞ©, Rβ = 5 kΞ©, and Rβ = 15 kΞ©. What will the voltage gain be?
π‘ Hint: Focus on how the resistors set the gain for both inputs.
