Challenge Problems
Push your limits with advanced challenges
In a voltage sampling feedback system, the output load introduces a resistance of 10k ohms. What is the effect on the sampling quality and system behavior, considering the previously discussed ideal conditions?
💡 Hint: Remember how resistance affects voltage measurements in real situations.
Design a feedback mechanism using both current and voltage inputs. Describe how you would select components to ensure minimum loading effects.
💡 Hint: Focus on how operational amplifiers can be optimally used here.
