There are hundreds of oscillator designs in use, and we won't get into that particular discussion, but again, any basic electronics design book is a good source for these designs. In the oscillator, the frequency of oscillation is usually determined by the value of a resistor, a capacitor, an inductor, or by an oscillating piezoelectric crystal, or a combination of each. Each of these components is reviewed later. For now, we want to review the properties and nomenclature associated with AC waveforms.

The same can be said of Rin also. "- \ \ \ \ I vout I I I / / I / Figure 1-19 rule. > for the circuit shown in Figure 1-20. 10n 1 50n .... -- I 10n "- 20n "- ,, \ \ \ r---- 100 v ( 5n $ \ \ VOUt , ~ 1 Figure 1-20 Circuit for Example 1-9. Solution: We see that Vin = 100 v. We must then find Rin. This value happens to be the circuit's total resistance across which the 100 volts is appearing. It is equal to: (10 1110) + 20 + 50 + (5 1116) To find V out , we must determine Finally, according to Eq.

Say - j In, has both magnitude and direction, just as an airplane fiying at 225 mph NW has both magnitude and direction. Figure 1-37 shows the coordinate system for the j-operator. Actually, most i-operators have associated with them a real number along with aj-operator number, or what some mathematicians call an imaginary number. A typical completej-operator plus real number would look something like 110 - jl72. This entire number is often referred to as a complex number. A plot of - i 172 and Ito - i 172 are shown in Figure 1-37, which also shows their vector quantities.
