Challenge Problems
Push your limits with challenges.
Question 1
You are tasked with designing a signal conditioning circuit for a medical sensor that operates at high frequencies while maintaining signal integrity. Discuss how a voltage follower could be implemented and the expected outcome.
💡 Hint: Focus on how impedance relationships affect high-frequency signals.
Question 2
A voltage follower is connected between a high-impedance source and a low-impedance load. If the source voltage varies, analyze how the voltage follower ensures the load receives a consistent voltage.
💡 Hint: Consider the role of high input impedance in ensuring minimal current draw from the source.
