PASSAGE
A communication channel passes analog frequencies up to 5 kHz. For digital baseband transmission, its maximum reliable bit rate is approximated by twice its bandwidth. A voice signal contains frequencies up to 4 kHz. One proposed digital system samples the voice at 8 kHz with 8 bits per sample and uses no compression.
Which conclusion follows from the channel limitations?
