In icrcuit passive case, the trajectory reaches the origin as t tends to infinity; we then called this circuit asymptotically stable. Loop and Cut-set Analysis Chapter Have doubts regarding this product? In this simple situation we can easily analyze the energy transfer and understand how such a circuit can become unstable.

Assume that the linear time-invariant network of Fig. Note that the second assumption is necessary because some passive linear time-invariant networks do not have a driving-point impedance, e. The current i t entering the port is called the port current, and the voltage u t across the port is called the port voltage. T60t – 6 cos 2’1Tl20t u12 thus contains the third harmonic as well as the second harmonic.

Some authors call our independent voltage source an “ideal voltage source. The precise relation between Band Q is stated in the following theorem.

Matrices and Determinants Appendix B: We shall see in the next section that the behavior of the impulse response of the network is also closely related to the location of the poles and the zeros.


Salient Features Novel formulation of lumped-circuit theory which accommodates linear and non-linear, time-variant and time-varying, and passive and active circuits. Given any lumped electric circuit and provided its elements have reasonably well-behaved characteristics, the equations of the circuit can be written as follows: The branch voltage due to the sinusoidal current described by 1.

The individual characteristics are shown in Fig.

Indeed, as shown by the characteristic for each value of the voltage u, there is one and circuuit one value possible for the current. Indeed, not only do the voltage sources and the current sources deliver energy to the circuit but also the mechanical forces that cause the elements to change their values.

It is true that one seldom finds a physical component that behaves as a linear active resistor as defined above. The inductor L is time-invariant. Calculate Vt, v2and V3.

This useful result will be encountered often in later chapters.

Demonstrate that the current gain is less than unity for the dual circuit. The entries of Table Summary For the series connection of elements, KCL forces the currents in allelements branches to be the same, and KVL requires that the voltage across the series connection be the sum of the voltages of all branches. We describe below only those fundamental properties of the Laplace transform that are useful to our study of linear time-invariant networks.

In modern parlance, the term “function” always means single-valued function, and the term “multivalued function” is slowly being replaced by “multivalued relation,” or simply “relation.


However, the model of a linear active resistor is important because a nonlinear resistor such as a tunnel diode behaves as a linear active resistor in the small-signal analysis.

Determine all branch currents and calculate the total power dissipation.

Charles a. Desoer, Ernest S. Kuh-Basic Circuit Theory(1969)

A linear resistor is both voltage-controlled and current-controlled provided 0 In physics we learned cidcuit 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.

Scal satisfies the initial conditions imposed on it. Size px x x x x Example 21 Consider the equation.

As we mentioned earlier, usual physical capacitors have a vq characteristic that is monotonically increasing; therefore, the instantaneous value of the charge q t can always be expressed as a single-valued function of the instantaneous value of the voltage v t.

This fact, as in the case of capacitors, is often alluded to by saying that “inductors have memory. 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. Their characteristics are shown in the vi plane of Figs.

The diode, the tunnel diode, and the gas tube are time-invariant resistors because their characteristics do not vary with time. Thus, linear time-varying resistors can be used to generate or convert sinusoidal signals.
