4. Consider a signal m(t) = 7t/3 forte [0.3) and m(t) = 7 fort € [3,5). The signal passes through a PCM system that quantizes the signal into four quantization levels in the interval (0,8). Four samples are taken at time t = 1,2,3,4. (1) (59) Draw m(t) with the quantization levels, their code number and binary representations. (2) (59) For the four samples, determine their sampled values (t), nearest quantization u(t), code numbers and their binary representations e(t). Solution: (1) Binary code Code Quantization Representation sumber level 8 6 - 4 2 2 (2) O 2 2 3 4 + 5 't sample value act) Nearest quantigation Ult) code number Binary code c(t)
