Multiple choice

A signal is sampled at 8 kHz and is quantized using 8-bit uniform quantizer. Assuming SNRq for a sinusoidal signal, the correct statement for PCM signal with a bit rate of R is

  1. R = 32 kbps, SNRq = 25.8 dB

  2. R = 64 kbps, SNRq = 49.8 dB

  3. R = 64 kbps, SNRq = 55.8 dB

  4. R = 32 kbps, SNRq = 49.8 dB
