Signal to noise ratio is infinite when(a) Quantization noise is zero(b

1.	Signal to noise ratio is infinite when(a) Quantization noise is zero(b) Number of levels are infinite(c) Quantization noise is zero & Number of levels are infinite(d) None of the mentionedI have been asked this question by my college professor while I was bunking the class.My question is taken from Sources of Corruption topic in portion Formatting and Baseband Modulation of Digital Communications
Answer» The correct OPTION is (C) Quantization noise is ZERO & Number of levels are infinite To elaborate: In the limit L tends to INFINITY and signal to quantization noise ratio tends to infinity when quantization levels are infinite and quantization noise is zero.
