MCQ Practice Question

If two identical noninteracting first-order amplifier stages are cascaded, the overall response near their individual cutoff frequencies is generally?

AExactly identical to one stage
BAffected because the stage responses multiply
CAlways flat at all frequencies
DIndependent of each stage response

Show AnswerHide AnswerReport an error

Correct Answer: B. Affected because the stage responses multiply

Explanation: The overall transfer magnitude is the product of individual stage magnitudes, so cascading alters the composite cutoff behavior.
