## Sayood, 3rd edition

- Page 25, line 11: Should be "H=-30/31 log 30/31 -1/31 log 1/31 = 0.206 bits."
- Pages 65-67: The description of Golomb codes is inconsistent.
One way of making it better is the following 5 corrections:
- Page 65, line -9: "positive" should be "non-negative"
- Page 65, line -7: Should be "... alphabet {0, 1, 2, ...} with ..."
- Page 65, line -5: Should be "P(k)=1/2
^{k+1}" - Page 66, line 8: Should be "integer n>=0 using ..."
- Page 67, line 2: Should be "P(n)=p
^{n}(1-p)"

- Page 71, table 3.22: "Probability" should be "Codeword".
- Page 97, line -1: should be
"u
^{(3)}=0.312+(0.6-0.312)F_{X}(2)=0.312+0.288*0.82=0.54816" - Page 100, line 17: should be
"u
^{(3)}=0.312+(0.6-0.312)F_{X}(2)=0.312+0.288*0.82=0.54816" - Page 185, equation 7.21: should be
"A
^{(n)}=A^{(n-1)}-q_{e}" - Page 238, line 8: should be "[-100, -1), (1, 100] with probability ..."
- Page 241, figure 9.10: The region for the overload probability should be everything outside [-4*delta, 4*delta].
- Page 256, table 9.6, second row of the 8-level gaussian quantizer: The decision boundary should be at 0.5005 and the reconstruction level should be 0.7560
- Page 336, formulas 11.36 and 11.37: To get the measures in dB, take the 10-logarithm of the ratios and multiply by 10.
- Page 400, formula 13.36: The first element in the matrix should be
x
_{00}. - Page 402, formula 13.43: The cosine factor for the case when i=0 can be removed, since cos(0)=1.
- Page 408, step 4 in the quantization algorithm: R
_{l}should be R_{1} - Page 408, step 4 in the quantization algorithm: After increasing
R
_{1}, the variance should be divided by 4. - Page 443, figure 14.15: The figure should look like

- Page 527, figure 16.12: The caption should be "Frame structure for layer 3."
