Sensors and Signal Conditioning, 2nd Ed. Ramon Pallàs-Areny and John G. Webster John Wiley & Sons, 2001, ISBN 0-471-33232 First-printing errata (Updated December 6, 2019) Page 13, last paragraph: Some sensors have an error (uncertainty) specified as… 20, eq. (1.6): change ( ) 2 2 ˆ − i n x x to ( ) 2 ˆ − i n x x . 22, table 1.3: ( ) arctan φ ωτ = . 25, first line after eq. (1.16): change τ to τ -1 . 29, last paragraph: …the frequency of resonance is not the same as the damped natural frequency, 2 r n 1 2 ω ω ς = (1.27) and the amplitude of that resonance at r ω ω = is M r : r 2 2 1 k M ζ ζ = − (1.28) 32, Table 1.6: after Temperature cycling add Atmospheric pressure . 37, figure 1.13, upper right: it should be T 2 > T 1 . 38, 3 rd . par., line 5: change ambient temperature to atmospheric pressure . 60, Example 1.5, a minus sign is missing: - 3 = 20lg a . 69, Problem 1.8, last line: …for the minimal damping ratio. 88, Fig. 2.11 a , b , and c : t should be italic. 91, last paragraph, line 7: ...tolerances at 0 °C introduce ±0.15 °C and ±0.30 °C uncertainty . 90, first equation should be: ( )( ) 0.1 °C 0.1 W/K 10 mA 100 = = Ω I 94, Fig. 2.14 a and b : t should be italic. 96, equation 2.24 should be (1/ T 2 – 1/ T 1 ) in denominator 101, first line after (2.37) should read: where T is in Celsius degrees . 127, eq. (2.55): Delete “=” before 1/V. 129, Problem 2.5, it should be δ = 18 mW/K. 140, Example 3.2: 2 r r 3 max 60 400 25 6.25 k 4 4 10 60 k 2.5 − > = Ω = × = = Ω V R P R R typical, and 12 k Ω minimum. Therefore, we can select R r = 10 kΩ. 153, Fig. 3.17 b , R w1 and R w2 should be a single wire, and the unlabelled wire next to R w3 should be R w2 157, missing absolute values in the numerators of the second equation. They should read: | v o – v i |, |- α T | 166, Fig. 3.29: the unlabelled resistor is R . 170, 3 rd . par., line 5: change Me lexis to Melexis . 202, Fig. P3.15, R 2 is the 500 Ω potentiometer. 209, first paragraph: change to The gap width w needed to achieve a relative error lower than a is w = -( d lna)/ π [5]. 281, eq. (5.5): change Z (1 – x ) to Z 0 (1 – x ) . 303, first equation: change v o ( t ) x ( t )/2 to v e ( t ) x ( t )/2 . 308, Fig. E5.6 legend: Amplifier . 310, Fig. 5.24: in switch S4 there should be a single arrow like that in S3. 314, two lines before eq. (5.50) it should read C x << C s . 326, references [11] and [12] should interchange their places. 333, first line after eq. (6.7): the respective absolute temperatures . 354, in eq. (6.30) it should be: dT + 367, first line before (6.50), it should be: From (6.4 8 ) we obtain
