(2) An analogue signal occupies a 5 kHz bandwidth. It is sampled at the minimum (Nyquist) rate, uniformly quantized and then represented using a PCM scheme with n quantization levels. It is then modulated and transmitted over a channel with bandwidth B = 60 kHz. Assume that B = 2/1, where t is the symbol duration. Determine the value of n if the modulation scheme is: (a) 8-PSK, [3 marks] (b) On-off ASK, and [3 marks] (c) QPSK. [3 marks]
