Question

Signal to noise ratio increases as ___________ increases.

(a) Quantization level

(b) Square of quantization level

(c) Square root of quantization level

(d) None of the mentioned

I got this question at a job interview.

I'm obligated to ask this question of Sources of Corruption topic in section Formatting and Baseband Modulation of Digital Communications

Answer 1

Right answer is (b) Square of quantization level

The explanation is: On calculating the number of levels, quantization error and power and also signal to noise ration we can find that signal to noise ratio depends directly on square of number of quantization levels.
