Appendix Scanning Code 128 Code Set A In .NET Framework Using Barcode Control SDK for .NET framework Control to generate, create, read, scan barcode image in Visual Studio .NET applications. Encode Code 128 In .NET Using Barcode creator for Visual Studio .NET Control to generate, create Code 128A image in .NET applications. the manner of Fig. 18A, approaching the limiting value of zero. Thus, as time increases, the voltage across the capacitor rises, in an exponentialtype curve, toward the nal limiting value of V volts. Letting vc denote the voltage across the capacitor, the relationship between vc and time t is shown graphically in Fig. 22A, the equation of the curve being vc V 1 t=RC 7A Code128 Decoder In .NET Framework Using Barcode decoder for .NET framework Control to read, scan read, scan image in .NET framework applications.

Making Code128 In VS .NET Using Barcode generator for ASP.NET Control to generate, create Code128 image in ASP.NET applications. Creating ANSI/AIM Code 128 In VB.NET Using Barcode creation for .NET framework Control to generate, create Code 128B image in VS .NET applications. Note that when t 0, then vc 0, as already mentioned and as shown in Fig. 22A. Then, as time increases, the term t=RC decreases exponentially toward the value zero (as in Fig. 18A). Thus, as t increases, the voltage vc increases toward the limiting value of V volts, as shown in Fig. 22A. In Fig. 22A, note that time is expressed in multiples of RC. This can be done because the product ohms times farads is time in seconds, as the following shows. First, by Ohm s law, R in ohms and then by eq. (184), C in farads hence, RC volts seconds coulombs seconds coulombs volts coulombs volts volts volts volts seconds amperes coulombs=sec coulombs Generate 2D Barcode In VS .NET Using Barcode generator for .NET Control to generate, create Matrix Barcode image in .NET framework applications. Code39 Creation In VS .NET Using Barcode maker for Visual Studio .NET Control to generate, create Code 39 Full ASCII image in VS .NET applications. The product, ohms times farads, is called the time constant of the basic series circuit of Fig. 21A. As Fig. 22A shows, at the end of one time constant (RC seconds) the voltage across the capacitor has risen to 63% of its nal value of V volts. (To show this, set t RC in eq. (7A).)

" " j Z Z Rotated through 90 Degrees
" Z A j
Let us make use of the exponential form of a complex number (section 6.5) as follows. " Let Z be a complex number of magnitude A and angle ; thus then " j Z Aj j But note that j908 cos 908 j sin 908 j; thus the preceding expression becomes " j Z A j908 j A j 908 " " showing that j Z is equal to Z rotated through 908. Note 17.
1/xC is in Ohms
From note 15, ! is measured in reciprocal time, 1=T, while capacitance C is measured in coulombs per volt, q=v (eq. (184) in Chap. 7). Thus 1=!C is basically measured in units of 1 volts volts ohms 1 coulombs coulombs=second* amperes second volts Note 18.
Harmonic Frequencies. Fourier Series
If any particular frequency, f, is taken to be a fundamental frequency, then any INTEGRAL MULTIPLE of f is said to be a harmonic of f. Thus, 2f is the second harmonic of f, 3f is the third harmonic of f, and so on, so that nf is any nth harmonic of f, where n 1; 2; 3; . . . (for n 1 we have fundamental instead of rst harmonic ). Now suppose we have some kind of nonsinusoidal function which occupies the interval from x 0 to x 2, and which is exactly repeated, over and over, endlessly, for all positive and negative intervals of 2, as in Fig. 23A. * Coulombs per second is amperes.
Appendix
Fig. 23A
It is a fact that ANY such repeating function, as met in engineering, can, for purposes of analysis, be considered to be composed of a FUNDAMENTAL sinusoidal wave plus, in general, an in nite number of sinusoidal harmonics of the fundamental wave.* This is a fact of great usefulness because it allows us, by the principle of superposition, to apply the ordinary algebra of complex numbers to the analysis of networks to which nonsinusoidal waves are applied. In such a representation, each complete fundamental wave (which is the lowest frequency component) covers a distance of 2 radians on the xaxis. Hence, in a distance of 2 radians there will be two complete second harmonic waves, three complete third harmonic waves, and so on. Let us discuss, as an interesting example, the symmetrical square wave of Fig. 24A.
