Your task is to transmit a voice signal of bandwidth 3.4 kHz over an AWGN channel. Assume the signal is sampled at 1.5 times the Nyquist rate and each sample is quantized into one of 256 equally likely levels.
a. What is the rate at which this voice source is generating information? b. Can you transmit the output of this source without error over an AWGN channel with a bandwidth of 10 kHz and an SNR of 20 dB? (Hint: The SNR is P/kT .) c. What is the minimum SNR required for error-free transmission of this information over the channel? d. Determine the minimum AWGN channel bandwidth required for error-free transmission of the output of this source if the SNR is 20 dB.
