What is meant by stability of an amplified signal in analog electronic circuits?
What is meant by stability of an amplified signal in analog electronic circuits?
Multiple Choice Options
- A✓ Correct Option
The amplified signal should not have self oscillation
- B
The amplified signal must have a finite amplitude
- C
The input and the output signal must be proportional
- D
The ratio of the input and the output signal must be finite
Detailed Technical Solution & Explanation
In amplifier design, circuit stability means the amplifier operates without entering unintended parasitic self-oscillation (Barkhausen criterion is avoided), maintaining bounded, stable output for bounded inputs.
Option Analysis:
•
Option A (The amplified signal should not have self oscillation): Correct. Freedom from spurious self-oscillation defines amplifier stability.
•
Option B (The amplified signal must have a finite amplitude): Relates to saturation/clipping.
•
Option C (The input and output signal must be proportional): Relates to linearity.
•
Option D (The ratio... must be finite): Relates to gain magnitude.
