How to Learn “Digital Logic Design”, online

Digital Logic Design has always been a new concept for fresh University students. Some find it interesting, while others find it “Difficult. I promise, this article will help you a lot. This scope of this article is, “How to learn it online”.
The best book on “Digital Logic Design” is written by “Morris Mano” and I have a very good version of it. You can buy its hard copy or download ebook or send me an email, i will mail it to you.
There are some extraordinarily good and simple video lectures available on www.youtube.com. Just type “Digital Logic Nptel”. Nptel is an Indian institution and they have good lecture series on various subjects, including “DLD”.
There is no shortcut to knowledge. DLD requires Logical understanding and you must take “Combinational Logic” and “Sequential Logic” and two separate entities, however, you can proceed to “Sequential Logic” after understanding the basics of “Combinational Logic”.
I got 4 GPA in DLD, by studying from the above mentioned sources.
It would be equally beneficial to develop a study approach. Example: If you want to understand counters you must understand Flipflops(FF) and to understand FF’s you need to understand “Latches”. So, “Latch” is the base of “Sequential Logic” and “Latch” is made of basic “NAND” or “NOR” gates, most commonly “NAND gates”.
The point is all concepts are interrelated. You must determine which concepts are required to understand the topic.
I forgot the most important point. Don’t Don’t Don’t ever study from too many books or the contemporary Notations and messed up diagrams will make your life worse than hell. If possible, take one good source and study from it. Don’t confuse yourself with different diagrams. Whenever, you have a problem with multiple information sources on DLD, simply refer to “Digital Logic Design” By “Morris Mano”.
Once you understand a topic, practice it again and again, without looking back at the source. Practice is equally important, as concepts. It happened to me, so, be cautious.
It is really funny but I have to mention it, for the sake of caution for others. I took my concepts to peak and paid a lot of attention to Complex Topics but paid less attention to “Karnaugh Map”. In my “Final Paper”, I designed “Synchronized clock 4 bit counters”, “Implemented Multiplexer based design” but was facing difficulty in simplification with “Karnaugh Map” All topics are equally important.
