← Logic & PuzzlesAn engineer increases the gain of a linear amplifier in a hearing aid. Which effect dominates?
A)Decreased battery lifespan observed
B)Reduced harmonic distortion measured
C)Increased output signal amplitude✓
D)Improved signal-to-noise ratio obtained
💡 Explanation
The amplifier's primary function is linear amplification; therefore, increasing the gain directly results in a larger output signal for the same input. This occurs because the gain linearly scales the input signal amplitude, rather than affecting battery life, distortion, or signal-to-noise ratio directly.
