Signal to quantization noise ratio in PCM system depends on _________(

1.	Signal to quantization noise ratio in PCM system depends on _________(a) sampling rate(b) signal bandwidth(c) number of quantization levels(d) nature of carrier waveThe question was posed to me in an international level competition.I'm obligated to ask this question of Applications of VSB topic in section SSB Modulation of Analog Communications
Answer» Correct OPTION is (c) number of quantization levels Easiest explanation: Pulse code modulation (PCM) is a digital form of communication. For demodulation of PCM, it is necessary to convert it into PAM. Quantization NOISE occurs in PCM only. SIGNAL to quantization noise ratio depends on the number of quantization levels.
