Challenge Problems
Push your limits with challenges.
Question 1
Explain how differential amplifiers can be utilized in a new smart sensor system designed for environmental monitoring and describe the benefits they provide over standard amplifiers.
💡 Hint: Consider the unique advantages in noise rejection for environmental contexts.
Question 2
A differential amplifier is used to read a signal from a temperature sensor that outputs a voltage of 0.2V. The output is set at 2V with a voltage gain of 10. If the sensor also picks up common-mode noise of 0.1V, how does the differential amplifier function to maintain accuracy?
💡 Hint: Focus on understanding how gain settings affect output in presence of noise.
