Challenge Problems
Push your limits with challenges.
Question 1
In a communications system with a differential amplifier of gain 50 and input signals of 1V and 2V, calculate the output voltage. Explain the significance of differential versus common mode gain in your findings.
💡 Hint: Use the formula for calculating output based on the differential gain.
Question 2
Consider a scenario where you have a noisy sensor output with noise that has a common mode gain of 5. If you implement a differential amplifier with a differential gain of 20, how would you evaluate the output? Calculate the output considering both gains.
💡 Hint: Analyze how noise influences your desired output signal.
