Unformatted text preview: division multiplex the two sequences. 5. The 10 sample values taken from a zero mean, variance 4 Gaussian distribution given by -2, -1.45, -0.2, +0.15, +0.24, +0.68, +2.2, +2.9, +3.6, +3.9, +4.95 are to be quantized using a 16-level MMSE Gaussian quantizer and encoded using a folded binary code. What are the resulting binary sequence and output amplitudes? 6. The uniform and nonuniform quantization tables in Chapter 9 of Sayood are for unit variance inputs. Show that if then we simply scale the quantizer step points and output levels by 2 1 σ > . From J. D. Gibson, Principles of Digital and Analog Communications , 1993....
