b- A PCM system uses a uniform quantizer followed by 7-bit encoder. The output bit rate is 50 Mbps. i) What is the maximum message bandwidth for which the system operates satisfactorily? ii) Determine the output signal-to- quantization noise ration if a full-load sinusoidal modulating wave of frequency \( 1 \mathrm{MHz} \) is applied to the system.
