D) determine the amplifier's input impedance

Question

Quizplus · Accepted Answer

The DC bias in an amplifier circuit is used to establish the desired operating point of the transistor or active device, ensuring it operates in the correct region (e.g., active region for linear amplification) for its intended application.
