Exercise 3 In the network of Fig. Let us now have an open circuit at port 1; then 5. Exercise Restate the definitions of a passive network and a passive one-port. For example, it is perfectly possible to have active elements in a network and still have the one-port of interest be passive, i. Then the right-hand side of 5.
Unfortunately, its proof is very complicated and would take us too far astray. A detailed discussion of this question is the subject of more advanced courses. By virtue of its nonlinearity, a nonlinear resistor has a characteristic that is not at all times a straight line through the origin of the vi plane.
Let a reciprocal two-port network be represented by its T equivalent, as shown in Fig. This property of the power dissipated is very interesting from a philosophical point of view. Clearly, to pump the maximum energy for a given displacement, we should wait for q2 t to reach a maximum; i. If the voltage Us ofa voltage source is identically zero, the voltage source is effectively a short circuit.
The integral in 3. Thus, for m linear resistors in parallel, we have Sec.

The following results, which give both the physical interpretations and the relations with the impedance and admittance parameters, are icrcuit derived: Enter email to get notified.
This fact is illustrated in Fig.
Matrices and Determinants Appendix B: As before we note that it is of the form 3. Again, superposition allows us to write the input variables V1 ,I1 in terms of the output variables Vz, – I2 by equations of the form 6.
The branch voltage across the capacitor can be computed immediately from Eq. If the resistance Rs is very small, the slope in Fig. The state moves along this trajectory in the clockwise direction. Example 3 The transistor amplifier in Fig.
A linear resistor is both voltage-controlled and current-controlled provided 0 In physics we learned that a resistor does not store energy but absorbs electrical energy, a capacitor stores energy in its electric field, and an inductor stores energy in its magnetic field. It is true that one seldom finds a physical component that edsoer as a linear active resistor as defined above.

Included in the book are enough additional materials to accommodate a full year’s course. Netviorks In this section we consider the behavior of a complete network, rather than its behavior at a particular port. For example, assume we have three zeros and four poles; the zeros z 2 and z2 and the polesp 3 andjs form complex conjugate pairs see Fig.
If all the voltage sources are transformed to current sources, then isk is the algebraic sum of all current sources in cut set k: Let fbe a function which maps X into Y, or f is a mapping or transformation or operator of X into Y. If the network has no coupling elements, the branch admittance matrix Yb jw is diagonal, and Yq jw is symmetric. Thus, the energy stored in the capacitor is, from 6.
The polynomialp can be found by substituting in 16 and equating coefficients of like powers oft.

In the passive case, the trajectory reaches the origin as t tends to infinity; we then called this circuit asymptotically stable. This result is the basis of practically all network synthesis.
Proof Integrating by parts, we have 2. Step I Find the poles and the zeros. Since the elements of the two-port are linear and since we seek only the zero-state response, the superposition theorem guarantees that each port current is the sum of the contributions due to each voltage source acting alone; therefore, in terms of Laplace transforms, the equations have the form 5.
The resulting waveform has u t – t 0 as an ordinate at timet.
