Question 1.
What is the differential mode gain if the input differential signal is 100mV?
Show hintHide hint
Multiply the input signal by the differential gain.
Question 2.
What is common mode gain?
Show hintHide hint
Think about signals that are identical at both terminals.
3Question 3.
What does a differential amplifier amplify?
- Only the common signal
- Only the differential signal
- Both signals
Show hintHide hint
Focus on the term differential.
4Question 4.
True or False: Common mode gain is always advantageous in improving signal quality.
- True
- False
Show hintHide hint
Consider the implications of noise.
Question 5.
Analyze how varying the common mode gain affects the overall output of a differential amplifier designed for high-fidelity audio amplification.
Show hintHide hint
Consider the implications on fidelity.
Question 6.
Construct a scenario where cascading differential amplifiers successfully filter out common mode signals, and provide calculations for expected outputs.
Show hintHide hint
Evaluate cascaded gains in series.
