4. Consider a signal m(t) = 7t/3 fort € (0,3) and m(t) = 7 forte (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) (5%) Draw m(t) with the quantization levels, their code number and binary representations. (2) (5%) For the four samples, determine their sampled values q(t), nearest quantization u(t), code numbers and their binary representations c(t). Solution: (1) Binary code Code Quantization Representation number level do 8 6 4 2 . 3 t 2 4 5 (2) sample value act) Nearest quantigation Ult) code number Binary code clt)
