Question 1.
What is the main function of a differential amplifier?
Show hintHide hint
Think about how it deals with input signals.
Question 2.
Define common mode gain.
Show hintHide hint
Consider the signals are identical.
3Question 3.
What does a differential amplifier primarily amplify?
- Common signals
- Differential signals
- Both types of signals
Show hintHide hint
Reflect on its primary function.
4Question 4.
True or False: A high common mode gain is desirable in differential amplifiers.
- True
- False
Show hintHide hint
Think about signal clarity and isolation.
Question 5.
A differential amplifier has a differential gain of 60 and a common mode gain of 4. An input differential signal of 150 mV is applied. Calculate the output and discuss the impact of common mode gain.
Show hintHide hint
Consider how common mode gain alters output.
Question 6.
If a differential amplifier exhibits a common mode gain of 10 and a differential mode gain of 100, discuss the implications for total system performance in a noisy environment.
Show hintHide hint
Evaluate the balance between gains for optimal functioning.
