Find the following: (a) The frequencies in x(t), and then draw its spectrum. (b) The value of the sampling frequency, and the specifications of the LPF to select only the first copy at the output of the sampler. (c) The number of quantization levels, and the bit rate of the PCM signal. (d) The minimum bandwidth of the channel to transmit the PCM signal without distortion.
