I've been enjoying the E-book for quite some time now and it has been a great supplement to my independent education. Thank you, E-book developers and sponsors! However, I've been investing a lot of time into finishing the E-book lately and I plan to be finished with Volume IV in the next couple weeks. So where do I go now? Many of the conversations on this forum still seem like Chinese to me, but I feel like most of the things discussed are more practical, hobbyist-related projects. I really DO want to be competent in that area, but I also want to have a stronger emphasis on theory as it pertains to more advanced digital and analog circuits, as well as more advanced electromagnetic theory. I especially want to begin studying the theory behind computer processors, in due time of course. As for computer programming, I decided to study that separately and I have plenty of sources. Can anyone recommend me to reliable and effective EE sources like the E-book that delve into more advanced topics?
