Q10) 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 = 40 kHz. Assume that B = 2/t, where t is the symbol duration. Find the value of n if the modulation scheme is: (a) On-off ASK, [3 marks] (b) QPSK, and [3 marks] (c) 16-PSK. [3 marks]
