Si un amplificateur devenait non linéaire, le signal de sortie:
- Aserait affligé de distorsion
- Bserait réduit à zéro
- Cprovoquerait des oscillations
- Dsurchargerait le bloc d'alimentation
Correct answer: A — serait affligé de distorsion. Question tirée de la banque officielle d'ISDE.
Why
When an amplifier becomes non-linear, it fails to copy the input signal perfectly, causing the output waveform to change shape and sound garbled, which is called distortion. The full explanation — and one for every question — is in Pro.
