Quantization noise can be reduced by ________ the number of levels.(a)

1.	Quantization noise can be reduced by ________ the number of levels.(a) Decreasing(b) Increasing(c) Doubling(d) SquaringI had been asked this question during an internship interview.This interesting question is from Pulse Code Modulation topic in section Formatting and Baseband Modulation of Digital Communications
Answer» RIGHT answer is (b) Increasing The explanation: The process of QUANTIZATION replaces the true signal with the APPROXIMATION(quantization noise). By increasing the number of quantization LEVEL the quantization noise can be reduced.
