3 cards from this section. Quick, good the night before a test.
Define common-mode signal.
Think about what two signals might have in common.
What is the purpose of a differential amplifier?
Focus on the role of the differential amplifier in signal processing.
What does a differential amplifier primarily do?
Think about what we learned regarding its functionality.
True or False: Common-mode signals are always undesirable in differential amplifiers.
Recall our discussions on the impact of these signals.
Design a differential amplifier circuit that could effectively reduce the impact of common-mode signals while amplifying a 20 mV differential input signal. Describe the steps you would take and the components needed.
Think of the circuit design aspects discussed in the class.
Analyze a signal processing scenario in a medical device where both common-mode and differential signals are present. What would be the consequences if the common mode gain is significantly high, and how can you mitigate this?
Consider the critical functions of medical devices when discussing signal clarity.
