A
The output remains linear and distortion is minimized
B
The output saturates to the supply voltage, causing signal distortion
C
The output is completely turned off, eliminating distortion
D
The output reflects the input voltage accurately without distortion
Understanding the Answer
Let's break down why this is correct
Answer
When the input voltage pushes the op‑amp beyond its supply‑rail limits, the device can no longer linearly amplify the signal, so its output is forced to sit at the nearest rail voltage. This “saturation” means the output no longer follows the input waveform and instead stays flat at the rail level. Because the output waveform is flattened, the shape of the signal is altered, producing harmonic distortion and clipping. For example, if a ±5 V powered op‑amp receives a 10 V peak sine wave, the output will be clipped to ±5 V, cutting off the peaks and distorting the waveform. Thus, exceeding the input range leads to saturation and significant signal distortion.
Detailed Explanation
When the input goes beyond the op‑amp’s limits, the device can no longer produce a proportional output. Other options are incorrect because The idea that the output stays linear is a misconception; Saying the output turns off is wrong.
