The sequence of a sampled signal is given as M = 9 1 2 3 3+0.2xM 4.8 Sample Sampled value/V 1.2 2+0.1xM = 2.9 If DPCM is used to encode the sampled sequence with 7-bit. (a) V and step size of the DPCM signal (b) The difference value d[2] and the decimal sequence for sample 2 (c) The difference value d[3] and the DPCM sequence for sample 3 (d) What are the two advantages of DPCM compared with PCM? What is the binary sequence for sample 2 and sample 3 if Delta Modulation is used?
