Fantastic practical introduction with emphasis on calculations, July 31, 2005
This review is from: The Analysis and Design of Linear Circuits, Fourth Edition (Hardcover)
Chapter 1 introduces basic concepts in electricity such as charge, voltage, current, resistance and Ohms law.
Chapter 2 then delves into basic DC circuit analysis of series and parallel circuits using KVL and KCL and the concepts of source transformation and circuit reduction.
Chapter 3 gives you more techniques to solve for difficult circuit analysis problems based on node and mesh analysis. Thevenin and Norton equivalent circuits are introduced.
Chapter 4 - so far the book has dealt with passive circuits. The authors now turn to active circuits. Transistors and OP amps are introduced with 4 basic signalling functions namely inverting/noninverting amps, diff amp and inverting summer. These are combined in different ways to give different signal processing properties. Analysis of op amp circuits is presented using nodal analysis techniques.
Chapter 5- now the authors deal with signal waveforms in particular step functions, exponential waveforms and sinusoidal waveforms.
Chapter 6 introduces the capacitor and inductor along with their I-V relationships and parallel and series reductions. These are then applied to active circuits and we obtain two other basic op amp circuits namely the integrator and differentiator.
Chapter 7 deals with 1st and 2nd order circuits so named since they are described by first and second order diff eq. RC and RL circuits are discussed followed by step and sinusoidal responses of 1st order circuits. RLC series and parallel circuits are next followed by step and sinusoidal responses of 2nd order circuits.
Chapter 8 is of a mathematical nature dealing with the use of phasors and sinusoidal steady state response. Phasor analysis is introduced with corresponding KVL and KCL laws and various circuit theorems. The concept of impedence is explained clearly.
Chapter 9 deals with Laplace transforms and their mathematical properties. One learns how to write them and to use the inverse transform to get back to the time domain from the "s" domain.
Simple circuit analysis using Laplace transforms is shown. One writes the diff eq for the circuit, converts it to s domain using laplace transform, you solve it using algebraic techniques and then use the inverse transform.
Chapter 10 gives you more theorems to use in s-domain analysis. The equivalent circuit theorems nodal and mesh analysis theorems are presented. We see that s-domain analysis is more than a mathematical trick rather it gives one deeper insight into the circuit. The natural poles allow one to determine the form, stability and observability of the circuits response.
Chapter 11 introduces the concept of network functions ( zero state response to input response in s domain ) in particular transfer ( different ports ) and driving point impedance ( same port ) functions and their use in circuit analysis. We also see how the use of transfer functions allows one to find a steady state response of circuit directly from the transfer function.
Chapter 12 deals with frequency response. Low pass, high pass, passband, and stopband concepts are introduced. Bode plots are explained.
Chapter 13 introduces fourier series and chapter 14 analog filter design
I did not read chapter 15 or 16
The book is replete with simple exercises progressing to more difficult ones with plenty of worked out examples.
A mature student can cover the material in most of the book in a few weeks . There are really very few basic concepts ( charge, voltage, current, I-V relationships in resistors, inductors, capacitors, natural generalization to impedance, Equivalent circuits with methods of reduction including KCL, KVL, parallel, series, Norton, Thevinen equivalents, nodal and mesh analysis concepts, active components and their properties, types of signal waveforms, steady state responses, phasor analysis, s-domain analysis using Laplace transform, network functions, frequency response principals of filter design and fourier series) numbering 30 or so that are combined in a straightforward way to solving circuit design and analysis problems.
This by no means indicates that circuit analysis and design is easy but rather like most other fields, the concepts are basic but their possible combinations and interactions are almost limitless. Often finding A solution is not enough. One must find a solution that meets several other criteria as well including multi-purpose use, cost efficiency, construction feasibility, etc.
