Q14) An analogue signal occupies a 2.5 kHz bandwidth. It is sampled at the minimum (Nyquist) rate, uniformly quantized and then represented using a PCM scheme with n quantization levels after which it is modulated and then transmitted over a channel with bandwidth B = 30 kHz. Assume that B = 2/t, where t is the symbol duration. Find the value of n if the modulation scheme is: (a) QPSK, [3 marks] (b) On-off ASK, and [3 marks) (c) 8-PSK [3 marks]
