Choosing a discrete value that is near but not exactly at the analog s

1.	Choosing a discrete value that is near but not exactly at the analog signal level leads to(a) PCM error(b) Quantization error(c) PAM error(d) Sampling errorThe question was posed to me in an internship interview.This is a very interesting question from Pulse Code Modulation in division Formatting and Baseband Modulation of Digital Communications
Answer» Right choice is (B) Quantization error To EXPLAIN: One of the limitations of PCM is quantization error which OCCURS when we choose a discrete value at some near by value and not at the analog signal level.
