(a) The message input of the Pulse Code Modulation (PCM) is given as follows: Am (t) = cos (20t) (i) Suggest the minimum sampling frequency and justify why this value suggested. Support your justification by illustrating its frequency spectrum w complete labels. (ii) If the message signal in quantized uniformly to 16,383 levels, calculate t number of bits required to encode the samples (iii)Evaluate the significant performance of the PCM if the quantization level reduced to 4 levels (iv)With the same quantization level in (c), suggest the compression characteris that will handle the given input signal voltage between -1 V to 1 V if t message signal use µ-law companding to provide non-uniform quantizatic Given µ=200. Support your answer with relevant complete illustration.
