Show hintHide hint
Think about how you would measure two points in a circuit.
Question 2.
What is common mode voltage?
Show hintHide hint
Consider what voltage is present on both terminals.
3Question 3.
What does differential voltage represent?
- The average voltage
- The difference between voltages
- The same voltage on both inputs
Show hintHide hint
Think about what it means to compare two voltages.
4Question 4.
True or False: Common mode voltage should be amplified in a differential amplifier.
- True
- False
Show hintHide hint
Consider the goal of amplifying only the desired signal.
Question 5.
