Question 1.
What does a differential amplifier mainly do?
Show hintHide hint
Think about what 'differential' implies.
Question 2.
What effect does applying the same voltage to both inputs have?
Show hintHide hint
Consider the nature of cancellation in signals.
3Question 3.
What is the primary function of a differential amplifier?

- To attenuate all signals
Show hintHide hint
Think about what 'differential' implies.
4Question 4.
If a signal is applied to both inputs of a differential amplifier, what is the expected result?
- True
- False
Show hintHide hint
Consider if inequality or equality affects output.
