This question was addressed to me during an online exam.

I would like to ask this question from Uniform and Non Uniform Quantization in division Formatting and Baseband Modulation of Digital Communications

Answer 1

Correct option is (b) Non uniform quantization

The explanation is: The human ear is sensitive to quantization error in small values so non uniform quantization is more preferable than uniform quantization.
