Challenge Problems
Push your limits with challenges.
Question 1
A lab experiment requires you to design an inverting amplifier that outputs -20V from a 5V input. If Rf = 50 kΩ, what should be the value of Rin?
💡 Hint: Rearrange the gain formula to find Rin.
Question 2
A summing amplifier is used to combine two signals: V1 = 4V and V2 = 6V. If Rf = 20 kΩ, what should R1 and R2 be for an equal weighting? Derive the output voltage.
💡 Hint: Ensure consistent resistor values for equal weighing.
