A System of Heuristic Means for Functional Operation with Basic Electronic Circuits
In fact, I started doing a free postgraduate study in 1989, at the Department of Pedagogy at VMEI "Lenin" - Sofia, on the topic of Computer-based educational technology for conducting educational laboratory experiments. Then I was inspired by the didactic possibilities of this approach in technical education. But the "wind of change" blew... and I changed my mind for a while.
Over the years, I gradually realized that my vocation was to reveal and explain the basic ideas behind circuits... and this led me to start a dissertation on this topic.
I uploaded this book to GoogleDrive as a pdf file in Bulgarian, and here I have placed only its contents in English. I will translate it in English but this needs time...
Go to the book!
