A signal band limited to 1 MHz is sampled at a rate 50% higher than the Nyquist rate and quantized into 256 levels. (a) Determine the signal-to-quantization-noise ratio. (b) The SNR (the received signal quality) found in part (a) was unsatisfactory. It must be increased at least by 10 dB. Would you be able to obtain the desired SNR without increasing the transmission bandwidth. If it was found that a sampling rate 20% above the Nyquist rate is adequate? If so, explain how. What is the maximum SNR that can be realized in this way?
