(d) i. With the aid of a block diagram, explain how a 128-Kbps rate is achieved for a Pulse Code Modulation (PCM) system for a voice. How many 128 Kbps links will fit in an E1 link? [4 marks] (e) For a WiFi system, a hot spot has a bandwidth of 30 MHz. i. Calculate the channel maximum capacity if the signal-to-noise ratio (S/N) is 60 dB, 30 dB, and 10 dB. [3 marks] ii. Comment on the practical usefulness of 0 dB S/N. [1 marks]
