A certain 8 bit uniform quantization PCM system can accommodate a signal ranging from - 1 V to + V. The rms value of the signal is 16-227-2 V . The signal to quantization noise ratio is:
[A]. 30 dB
[B]. 46.91 dB
[C]. 40 dB
[D]. 49.92 dB

Answer: Option D

Explanation:

SNR)dB = 1.76 + 6.02n

n = 8

Thus (SNR)dB = 1.76 + 6.02 x 8 = 49.92 dB.
