A)small signals only
B)large signals only
C)both large and small signal
D)no signal

Question

Quizplus · Accepted Answer

Transistors behave as linear devices when dealing with small signals. This is because, for small signals, the transistor operates in its active region, where the relationship between input and output can be approximated as linear. For large signals, non-linearities become significant, moving the operation outside the linear region.
