This concept of enlarging the domain of the function is usually referred to as analytic continuation. However, for a nonbilateral element such as a hteory, one must know the terminal designation exactly. The course consists of three lectures and one two-hour recitation per week. It is natural to use the uncharged state of the capacitor as the state corresponding to zero energy stored in the capacitor.
This property of linear time-varying resistors is referred to as “modulation” and is of great importance in communication systems. In most of our applications the Laplace transforms will turn out to be rational functions.
A typical example of a nonlinear resistor is a germanium diode. The following results, which give both the physical interpretations and the relations chzrles the impedance and admittance parameters, are easily derived: Note that in these loop equations all char,es voltages except independent sources must be expressed chxrles terms of the variables chosen in Step 2.
Let the two resistors be specified by their characteristics, which are shown in Fig. In practice, this is done by using a bias circuit containing a battery. We shall treat passive networks, linear as well as nonlinear, and we shall show that the energy stored in passive networks in general has interesting properties; in particular, passive networks cannot be unstable.
In the preceding examples, we have said “the chharles state is specified by The port concept is very important in circuit theory. Let us note in passing that at tr, t 3t 5. The book ends with three appendixes devoted to basic mathematical topics: In this section we shall give four descriptions of this kind.

Under the above situation, what can you say about the voltages v1 and v2? It is customary and convenient to use reference directions for the branch voltage and the branch current of an independent source that are opposite from the associated reference directions. Unfortunately, its proof is very complicated and would take us too far astray.
It is possible and often more convenient to use a mixed set consisting of one current and one voltage as the independent variables and the remaining parameters as the dependent variables. Show that the series connection has the characteristic shown in Fig l. If the network is resistive and if all branch resistances are positive, then det Yq 0.
Since the energy in joules is the integral of power in wattsit follows that the energy delivered by the generator to the one-port from time t0 to time t is 6.

Nodes A and Bare also connected to the rest of the circuit designated by Set up the network equations and solve them to obtain i 1 ti 2 tand i3 t for t 0. The reference directions are shown in Fig. We have shown ttheory the driving-point impedance of any one-port made of passive linear time-invariant elements is positive real.
On the other hand, if a constant voltage source is connected in series with a diode, the conditions of 3. We shall encounter this important chales throughout our study of circuit theory. To know the function logarithm, we need a whole table consisting of the collection of all ordered pairs x, log x.
Note that, irrespective of the sign of q, we must apply a force to the moving plate in the direction of increasing x. Therefore, for small currents the nonlinear resistor may be approximated by a linear ohm resistor. This result is the basis of practically all network synthesis. C t u t u t where we use the dot over C to denote the derivative cuarles C.
To our best knowledge there is no effective way of describing the general hysteresis phenomenon. Included in the book are enough additional materials to accommodate a full year’s course. It is connected in series with an arbitrary independent voltage source vs t as shown in Fig. The state-space method is introduced and illustrated with both linear and nonlinear circuits. More formally, we state the following theorem.

Determine the value of gm for which the conductance matrix is singular. This poses no problem, since a given network driven by voltage sources can be ccircuit into a network with equivalent current sources. Note that in these cut-set equations all branch currents must be expressed in terms of the variables chosen in Step 2. So for convenience, we shall often say “the wave- Sec. Safe and Secure Payments.
