The student is asked to identify certain components in the diagram, describe their operation, modify circuit elements, and design new circuit interfaces. This gives the student experience working with real-world, large-scale schematics like the ones that he or she will see on the job. Several EWB exercises are included at the end of each chapter. One of the CDs included in the back of this textbook contains all of the circuit files and instructions needed to solve each problem.
There are three types of problems: 1 circuit interaction problems require the student to change input values and take measurements at the outputs to verify circuit operation, 2 design problems require the student to design, or modify, a circuit to perform a particular task, and 3 troubleshooting problems require the student to find and fix the fault that exists in the circuit that is given. Designing digital logic with CPLDs is becoming very popular in situations where high complexity and programmability are important.
The CPLD problems use manufacturers' software to solve designs that were previously implemented using series ICs. Examples of circuit design are provided within the chapters, and Appendix E contains tutorials for using the software. Several annotations are given in the page margins throughout the text.
These are intended to highlight particular points that were made on the page. They can be used as the catalyst to develop a rapport between the instructor and the students and to initiate team discussions among the students.
Four different icons are used to distinguish between the annotations. Common Misconception: These annotations point out areas of digital electronics that have typically been stumbling blocks for students and need careful attention. Pointing out these potential problem areas helps students avoid making that mistake. Team Discussion: These annotations are questions that tend to initiate a discussion about a particular topic.
The instructor can use them as means to develop cooperative learning by encouraging student interaction. Helpful Hint: These annotations offer suggestions for circuit analysis and highlight critical topics presented in that area of the text. Students use these tips to gain insights regarding important concepts.
Inside Your PC: These annotations are used to illustrate practical applications of the theory in that section as it is applied inside of a modern PC. This will help the student to understand many of the terms used to describe the features that define the capability of a PC.
I would like to share with you some teaching strategies that I've developed from using this text for the past 14 years. Needless to say, students have become very excited about learning digital electronics because of the increasing popularity of the digital computer and the expanding job opportunities for digital technicians and engineers. Students are also attracted to the subject area because of the availability of inexpensive digital ICs, which have enabled them to construct useful digital circuits in the lab or at home at a minimal cost.
Student Projects: I always encourage the students to build some of the fundamental building-block circuits that are presented in this text.
Practical Digital Electronics for Technicians covers topics on analog and digital signals, logic gates, combinational logic, and Karnaugh mapping. The book. ecmerweaha.tk: Practical Digital Electronics for Technicians (): Will Kimber: Books.
Having these circuits provides a starting point for the student to test many of the other circuits in the text at his or her own pace, at home. Team Discussions: As early as possible in the course, I take advantage of the Team Discussion margin annotations.
These are cooperative learning exercises where the students are allowed to form teams, discuss the problem, and present their conclusion to the class. These activities give them a sense of team cooperation and create a student network connection that will carry on throughout the rest of their studies. Laboratory Component: Giving the students the opportunity for hands-on laboratory experience is a very useful component of any digital course.
An important feature of this text is that there is enough information given for any of the circuits so that they can be built and tested in the lab and that you can be certain they will give the same response as shown in the text. Circuit Illustrations: Almost every topic in the text has an illustration associated with it. Because of the extensive art program, I normally lecture directly from illustration to illustration. To do this, I have an overhead transparency made of every figure in the text. Testing: Rather than let a long period of time elapse between tests, I try to give a half-hour quiz each week.
Besides the daily homework, this forces the students to study at least once per week. This sheet can have anything they want to write on it. Making up the formula sheet is a good way for them to study and eliminates a lot of routine memorization that they would not normally have to do on the job. The Learning Process: The student's knowledge is generally developed by learning the theory and the tools required to understand a particular topic, working through the examples provided, answering the review questions at the end of each section, and finally, solving the problems at the end of the chapter.
I always encourage the students to rework the solutions given in the examples without looking at the solutions in the book until they are done. This gives them extra practice and a secure feeling of knowing the detailed solution is right there at their disposal. Basically, the text can be divided into two halves: Chapters 1 to 8 cover basic digital logic and combinational logic, and Chapters 9 to 17 cover sequential logic and digital systems.
Chapters 1 and 2 provide the procedures for converting between the various number systems and introduce the student to the electronic signals and switches used in digital circuitry. Chapter 3 covers the basic logic gates and introduces the student to timing analysis and troubleshooting techniques. Chapter 4 explains how to implement designs using CPLDs. Chapter 5 shows how several of the basic gates can be connected together to form combinational logic.
Boolean algebra, De Morgan's theorem, and Karnaugh mapping are used to reduce the logic to its simplest form. Chapters 6, 7, and 8 discuss combinational logic used to provide more advanced functions like parity checking, arithmetic operations, and code converting. The second half of this book begins with a discussion of the operating characteristics and specifications of the TTL and CMOS logic families Chapter 9. Chapter 10 introduces flip-flops and the concept of sequential timing analysis.
Chapter 11 makes the reader aware of the practical limitations of digital ICs and some common circuits that are used in later chapters to facilitate the use of medium-scale ICs. Chapters 12 and 13 expose the student to the operation and use of several common medium-scale ICs used to implement counter and shift register systems. Chapter 14 deals with oscillator and timing circuits built with digital ICs and with the timer IC.
Chapter 16 covers semiconductor, magnetic, and optical memory as it applies to PCs and microprocessor systems. Chapter 17 introduces microprocessor hardware and software to form a bridge between digital electronics and a follow-up course in microprocessors. The book concludes with several appendices used to supplement the chapter material. If time constraints only allow for a single-semester course, then the following sections should be covered to provide a coherent overview of digital electronics:. Sections 1. Also, if the course is intended for nonelectrical technology students, then the following sections could be omitted to eliminate any basic electricity requirements:.
Sections 2. Special features included in this textbook to enhance the learning and comprehension process are:. An extensive package of supplementary material is available to aid in the teaching and learning process. The first five editions were developed from an accumulation of 18 years of class notes.
Teaching from the fifth edition for the past 3 years has given me the opportunity to review several suggestions from my students and other faculty regarding such things as ways to improve a circuit diagram, clarifying an explanation, and redesigning an application to make it easier to duplicate in lab.
More than schools have adopted the fifth edition. To write the sixth edition, I have taken advantage of the comments from these schools as well as my own experience and market research to develop an even more practical and easier-to-learn-from textbook. Besides rewriting several of the examples and applications based on my classroom experience, I have added the following material:. Digital electronics is the foundation of computers and microprocessor-based systems found in automobiles, industrial control systems, and home entertainment systems.
You are beginning your study of digital electronics at a good time.
Technological advances made during the past 25 years have provided us with ICs that can perform complex tasks with a minimum amount of abstract theory and complicated circuitry. Before you are through this book, you'll be developing exciting designs that you've always wondered about but can now experience firsthand.
The study of digital electronics also provides the prerequisite background for your future studies in microprocessors and microcomputer interfacing. It also provides the job skills to become a computer service technician, production test technician, or digital design technician, or to fill a multitude of other positions related to computer and microprocessor-based systems.
This book is written as a learning tool, not just as a reference. The concept and theory of each topic is presented first. Then, an explanation of its operation is given. This is followed by several worked-out examples and, in some cases, a system design application. The review questions at the end of each chapter will force you to dig back into the reading to see that you have met the learning objectives given at the beginning of the chapter. The problems at the end of each chapter will require more analytical reasoning, but the procedures for their solutions were already given to you in the examples.
One good way to prepare for homework problems and tests is to cover up the solutions to the examples and try to work them out yourself. If you get stuck, you've got the answer and an explanation for the answer right there. The more practice you get, the easier the course will be.
I wish you the best of luck in your studies and future employment. See All Customer Reviews.
