(c) A single voice channel is encoded using PCM. 8,000 samples/seconds are taken and 7-bit quantization is used. The resultant binary stream is then transmitted via binary transmission. (i) Calculate the bit rate for the PCM coded binary stream. (ii) If PSK is used for transmission, describe the modulation process and calculate the bandwidth. (iii) If ASK is used for transmission, describe the modulation process and calculate the bandwidth.
