Question 1.
Define single-ended and differential signaling.
Show hintHide hint
Think about how signals are referenced.
Question 2.
What is differential mode gain?
Show hintHide hint
It's related to how well you can amplify the difference.
3Question 3.
What is the primary function of a differential amplifier?
- A. Amplify noise
- B. Amplify the difference between two signals
- C. Provide a single-ended output
Show hintHide hint
Think about what differential amplifiers aim to do.
4Question 4.
True or False: Common mode gain should be kept high to improve signal clarity.
- True
- False
Show hintHide hint
Consider how noise affects the desired signal.
Question 5.
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.
Show hintHide hint
Use the formula for calculating output based on the differential gain.
Question 6.
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.
Show hintHide hint
Analyze how noise influences your desired output signal.
