3.
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
[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.

SQNR= 1.5*(2^2n) by converting this factor in db will get SQNR IN DB = 1.8+6n where n is no of bits per sample.
