Reinventing Circuits
By the mid-1990s, I had already developed my own philosophy about electronic circuits, and I decided it was time to share it with my colleagues. In the spring of 1997, I presented a series of three papers at the XXXII Scientific Conference on Communication, Electronic and Computer Systems at the Technical University of Sofia. The first of these was devoted to my heuristic course on analog circuits, in which I had implemented my circuit philosophy. There I shared my idea of reinventing circuits for the purposes of understanding, presenting and inventing circuits. In this post, I will tell you about this venture of mine.
The Idea
The idea of the heuristic approach in circuitry is simple - ''instead of presenting the circuits in their complete and perfect form, we reinvent them''. Thus, we can delve deeply into the essence of phenomena, realize the meaning of technical solutions and develop heuristic thinking. This will allow us not only to analyze the operation of electronic devices, but also to create, synthesize, why not actually invent them?
Examples
- From Ohm's basic electrical circuit we can "invent" six passive analog devices: ''voltage-to-current'', ''resistance-to-current'', ''current-to-voltage'' and ''resistance-to-voltage converters''; ''voltage/current divider''; ''current x resistance multiplier''.
- Thevenen and Norton's real electrical circuits give us the idea of a ''voltage'' and ''current divider''. From Kirchhoff branch circuits we naturally obtain the ''parallel current summer'' and the ''series voltage summer''.
- The reactive elements capacitor and coil can play the role of ''current'' and ''voltage integrators'', etc.
