← ScienceWhich instability results when parasitic capacitance couples amplifier stages?
A)Spurious oscillation initiates unpredictably✓
B)Gain compresses as voltage drops
C)Harmonic distortion reduces fidelity
D)Dead zone introduces non-linearity
💡 Explanation
Spurious oscillation can initiate in amplifiers because unwanted inductive coupling forms resonant circuits; this is Parasitic oscillation. Therefore, the amplifier oscillates rather than amplifying faithfully because oscillations are reinforced, and alternatives involve other distortions.
