What is a differential amplifier designed to do?
Remember its primary function.
Define a common mode signal.
Think of noise shared between two lines.
What does a differential amplifier primarily amplify?
Focus on the term 'differential'.
True or False: Common mode signals are desirable when using a differential amplifier.
Think about the purpose of the amplifier.
An audio signal is sent over a long distance, but due to ground potential differences, noise is introduced. How can a differential amplifier help in such a scenario?
Focus on how the amplifier processes both signals.
Define the common mode rejection ratio and its significance in the performance of a differential amplifier.
Think about how we quantify the effectiveness of noise suppression.
