I've been looking for quite some time for some tutorial/video online explaining a working circuit. I mean, consider some simple analoge circuit, with resistors and voltage dividers, caps, maybe even transistors etc etc... If this circuit performs some understandable task, then what do these "helper components" do? I gather a lot is to do with ensuring the proper voltage and/or current "at" the various legs of the "more important" (active) components (transistors, mosfets, IC's etc). But while I understand there's a lot more to take into consideration than simply "powering on" transistors to make them do useful work, but what -- then -- do the resistors do for instance in the audio circuit ("fuzz") below?
The caps are there to prevent the DC powering the transistors "inside" the effect circuit from going along with the audio signal (which is AC) at the input and output. This could possibly damage the guitar and/or amp :-)
In summary, does anyone know of a resource which takes "simple" circuits one can relate to, and breaks them down discussing the design? I know there are tons of stuff going the opposite direction (explaining the basic theory), but it would be so much more motivating to see something like this after struggling with the theory (as a hobby) for years.Joakim
