  • Question

  • 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 certain 8 bit uniform quantization PCM system can accommodate a signal ranging from - 1 V to + V. V . The signal to quantization noise ratio is:


  • Options
  • A. 30 dB
  • B. 46.91 dB
  • C. 40 dB
  • D. 49.92 dB

  • Correct Answer
  • 49.92 dB 

    Explanation
    (SNR)dB = 1.76 + 6.02n

    n = 8

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