An analog speech signal is sampled at a rate of \( 8 \mathrm{kHz} \), quantized and encoded using 8-bit ADC. Design a passband transmission system to transmit the digital sequence through a passband channel with bandwidth \( 16 \mathrm{kHz} \). If there are multiple solutions, please select one that you believe the best and explain your reason.
