Question 1.
What is a differential amplifier?
Show hintHide hint
Think about what signals it is designed to measure.
Question 2.
How does a common emitter configuration change the output signal?
Show hintHide hint
Consider how the input and output relate in terms of phase.
3Question 3.
What is the primary function of a differential amplifier?
- Amplifying common signals
