The ratio of average signal power and quantization noise is(a) 3L^2(b) L^2/3(c) 2L^3(d) L^3/2This question was posed to me during an interview.My question comes from Sources of Corruption topic in portion Formatting and Baseband Modulation of Digital Communications

Answer»

The CORRECT option is (a) 3L^2

The BEST explanation: On calculating the signal power and the quantization NOISE, and on taking its ratio it depends on the number of quantization level L and we get as 3L^2.
