Basic Electronics Erratum Page


List of known erratum in the 2010 version
In May 2010, the erratum found in the 2009 version
were fixed and an updated version of the text was produced. The updated version
has (C) 2009, 2010 at the top of page ii. The following list is based on the book
currently available on lulu.com
 Page 21,
In the second row of the middle column of table 1.3, the voltage should be V_{0}/3.
List of known erratum in the 2009 version
During the summer of 2009, an updated version of the text was
produced that corrected the errors found to date. The following list is based on the book
that has (C) 2009 at the top of page ii. If you are using a used book, these are likely to
apply to your book.
 Page 11,
The formula for i_{1} and R_{eq} in the top half of the page should have
(N_{1}/N_{2})^{2} in them. (This is inverted from what is shown in
the text.)
 Page 14,
The value of R_{s} at the bottom of the page should be 0.01 Ohms.
 Page 15,
The value of R_{m} at the top of the page should be 0.01 Ohms.
 Page 23,
In the middle of the second paragraph, the expression `` V_{th},
(I_{N}/R_{N})'' should be ``V_{th}, (I_{N} * R_{N})''.
 Page 92,
The second equation (near the top of the page) should be
tan(phi_{L}) > (omega omega_{LR})/(omega_{LC}^2) and in the
following equation, the limit should go to pi (180 degrees).
 Page 93,
In figure 3.14, the Bode plot is reversed lefttoright.
 Page 131,
in formula 4.11, the n in the exponential should be an m.
 Page 164,
formulas for i_{out} and V_{out} at the bottom of the page.
Both formulas should be over R_{C}+R_{L}
 Page 166,
in the middle of the page, the values for R_{1} should be 10.4kOhm and
R_{2} should be 1.11kOhm. These change then impact the calculation following. We find
that C_{1} is greater than 29 microFarads.
 Page 167,
the values in the table are changed due to the previous errors in the text.

Desired Value 
Obtainable Value 
R_{E}  1kOhm  1kOhm 
R_{C}  10kOhm  10kOhm 
R_{1}  10.4kOhm  10kOhm 
R_{2}  1.11kOhm  1kOhm 
C_{1}  29muF  33muF 
C_{2}  3.2muF  3.3muF 
 Page 167,
In the expresion for Z_{out} in the middle of the page, the last term should be
R_{E}/beta and not R_{C}/beta.
 Page 168,
In figure 5.25, R_{5} should be R_{3}.
 Page 190,
The second formula on this page should be I_{C}=beta * I_{B}.
 Page 205,
in Figure 6.11, the inputs to the opamp are reversed. The inverting input should
be on top. Related to the flip in the figure, the text above describing which
inputs v_{1} and v_{2} go into needs to be reversed.
 Page 205+206,
the derivation for the output voltage of the differential amplifier has a number of
problems. A cleaner derivation is as follows. First, we note that
v_{out}=R_{2}/R_{1}(v_{1}v_{2}). The voltage
at the noninverting input is
v_{+}=v_{2}R_{2}/(R_{1}+R_{2}).
By our opamp rule, the voltage at the inverting input is equal to this. The input
at the inverting input is also given by
v_{}=v_{out}+(v_{1}v_{out})R_{2}/(R_{1}+R_{2}).
These two expressions for v_{} can be equated to yield
v_{out}=(R_{2}/R_{1})(v_{1}v_{2}).
 Page 241,
At the end of the first paragraph in section 7.2.2 Negative Numbers, the range should be:
(2^{(n1)}1) to (2^{(n1)}1).
 Page 260,
Table 7.20 has the R and S labels swapped for the two coloums. The column headers
should read V^{P}, S, R and O.
 Page 265,
Just above figure 7.33, the formula
C_{2}C_{3}/(C_{2}+C_{3}) >> C_{0}
should read:
C_{3}C_{4}/(C_{3}+C_{4}) >> C_{2}.
Also, just after this, we should choose C_{3}=C_{4}.
 Page 273,
In the formula in the center of the page, we should have
V_{ref} = (1/2^{n})(v_{max>}v_{min}),(2/2^{n})(v_{max}v_{min}), ... , ((n1)/2^{n})(v_{max>}v_{min})
 Page 275,
The feedback resistor in figure 7.43 should be 2R and not just R.
 Page 323,
The solution to problem 1.16 sould be V_{th}=V_{0} and R_{th}=R_{2}.
 Page 324,
the answers to 3.9(e) and 3.9(f) are reversed.
