The Internet vs. Text Books; for the ultimate resource

Catwell
Catwell over 15 years ago
I was speaking with an engineer friend of mine the other night, and I asked him what reference does he use most during development. To my surprise, he uses his old college text books. He said, "the books always have a clear explanation of whatever the challenge might be." "The Internet," he went on, "is usually convoluted, not clear, or about one specific part, and almost never tells me how and why I should use any one particular method." My friend, here, was the type that never rushed to sell back his $100 dollar book for $15. He kept every last one. I still have a few left over, but now I am thinking I should go buy recent copies of every EE class's book. I often spend a lot of time sorting through expansive forums for the smallest bit of info.
 
Another friend of mine is all about the Internet reference. He always consults Wikis, forums, school websites for all his information. On occasion, he would spend most of the day researching a design online, and come back with examples and preliminary. He has said, "everything I need is there [on the Internet].  Even actual real world examples, samples, and even complete designs." I will admit to doing this at some of level for projects, especially with code.
 
Everyone has their own method for design. Ultimately, whether you are by the book or gleam from web, you have to deliver on the project. Weigh in on which side you choose, and why.

    Hi Cabe,

     

    Excellent topic, I rely extensively on my textbooks whenever I do a project. Textbooks are edited and you can always confirm the source of the information so you know that whatever you find is proven info and reliable. I can't say I have the same security with the internet, I can't tell you how many times I've read posts or internet articles by people who have no background or are clearly misinformed and shuttered to think what would happen if anyone were to rely on the information provided by them.

     

    The other good thing about textbooks is that they are generally oriented towards teaching you how to solve problems, giving you the tools you need to be able to analyze engineering problems in a systematic manner. Most of the time, on the internet you find answers with little or no information as to how those solutions are derived and here's the biggie, how they can be modified for various purposes.

     

    If you don't know the in and outs of a circuit then you can only use it in the manner that has been shown to you. When you completely understand the inner workings of an IC then you can devise applications for it that maybe no one else has thought of. The only way to do that is fully understand a circuit and how it is created, I just don't feel the internet does that.

     

    Now this isn't to say the internet is evil and should never be used by serious engineers. Manufacturer App Notes and example code are invaluable resources and these can only be found online. Open source is another good reason to use the internet as many products today incorporate elements that were created by open source communities, some times you can get inspiration from these projects.

     

    I don't think it's possible to be completely reliant on one or the other, but I'll take a textbook over a web search any day.

     

    My 2 cents,

    Jorge Garcia

    Jorge, Ken,

     

    Since now I am on a quest to collect the best text book references, what do you use? ISBN #s?

    Hi Cabe,

     

    Here are a few suggestions in no particular order,

     

    1)  ARRL Handbook- Excellent overall reference on everything electronic,  one to keep handy. Lots of useful information on Filter Design and  Impedance matching it's updated every year and they are constantly  adding new sections. Don't look for mathematical rigor, but it's  explanations are concise and give lots of Ideas.

     

    2)  Microelectronic Circuits by Kendra and Smith- Authoritative text on  Semiconductor Theory. Transistors, Diodes, and Op Amps are covered in  Detail I especially find useful the final chapters of the book since  they are more applications oriented.

     

    3)Learning to Fly  the PIC24 by Lucio DiJasio- IMHO the best book to have on the PIC24 and  dsPIC family of microcontrollers, easy to follow examples and highly  commented code written in an informal style. He also covers many of the  advanced features of the MPLAB IDE, one of the best references I have.

     

    4)Switching  Power Supply Design by Pressman, Billings- Hands down the best book on  the subject covers everything you need to know to design your own  switching power supplies, magnetics, control loop compensation,  topologies etc.

     

    5) Control Systems Engineering by Nise-  Authoritative text on Control System Design and feedback theory, I've  used it a lot when designing.

     

    6) Electric Circuits by  Nilsson and Riedel- I have the 8th Edition they've supposedly release  the ninth, awesome book to have to review the basics of circuit theory,  kvl, kcl, thevenin, norton, fourier transforms, laplace transforms,  two-port network theory. Also a highly used reference.

     

    Hope these give you some ideas if you search through amazon they'll pop right up.

    Jorge,

     

    Great list, thank you. I am going to see if I can get all these cheap online somewhere.

     

    Which ones from your list were your old college textbooks?

    Hi Cabe,

     

    With the exception of the Handbook and the Switching Power Supply Book I used all of those books in college. There are good textbooks for every discipline so I would suggest that if money is tight try to get the textbooks that tailor to the subjects your interested in, those will be the ones you use the most.

     

    For example, when I started my first engineering job I was assigned to design the switching power supplies and drivers since I had no previous background (Never took a power electronics course in College) I looked through the tables of contents for all of the power supply texts I could find on Amazon and decided this the book by Pressman and Billings would be the most comprehensive, man did I make a great choice.

     

    In my experience, you can make a good estimation of a textbook by reading the table of contents.

     

    hth,

    Jorge,

     

    From experience, a lot of engineers are lacking in the power supply design department, and they all need a good reference book on the matter.

     

    What is the exact name of the book you bought that helped you? ISBN number?

    Thanks Jorge.

     

     

    That is a very expensive book. $78 dollars on amazon!

     

    Anyone have a copy they would like to sell?
