3 cards from this section. Quick, good the night before a test.
What is a differential amplifier?
Think of how it deals with unwanted noise.
Define common mode signal.
What interference appears on both input lines?
What is the primary function of a differential amplifier?
Remember what makes differential amplifiers unique.
True or False: Differential signaling can help mitigate noise while transmitting signals.
Think about the nature of the signals being sent.
Suppose you have a differential amplifier with a differential mode gain of 100 and a common mode gain of 0.01. Analyze the effect of these gains on signal clarity in a practical scenario.
Consider how these gains interact when signals are transmitted.
In a communication system, the transmitted pair of signals experiences a common mode noise of 200 mV while the true differential signal is only 50 mV. Discuss the feasibility of distinguishing the true signal using a differential amplifier.
Examine the relative sizes of the signals.
