Question 3 (25 marks) An analog voltage waveform w(t) with a bandwidth of 2 kHz is converted into binary PCM signal for transmission using digital modulation. a) (3 marks) Determine the Nyquist rate (i.e., the minimum sampling rate needed). b) (5 marks) If the signal-to-noise power ratio at the output of the quantizer is required to be at least 36 dB, determine the minimum number of bits in each PCM word. c) (3 marks) With the number of bits obtained in part b, determine the bit rate of the PCM signal if w(t) is sampled at its Nyquist rate.
