← TechnologyWhich outcome results when an audio signal experiences companding?
A)Reduced quantisation noise perceived✓
B)Increased dynamic range overall
C)Higher frequency response obtained
D)Lower total harmonic distortion
💡 Explanation
Companding uses nonlinear encoding, applying compression before transmission and expansion at reception; this increases signal-to-noise ratio because quieter signals receive more bits, therefore perceived quantisation noise is reduced significantly rather than increased distortion at louder signal levels.
