Hi there all! I am sitting for an electronics subject for an Applied Physics course I'm studying here in Greece, but as the educational system does not make you attend the courses (in class), I don't have any solved exercises on Electronics! I made a quick search all over the net, found many guides and complany stuff, but none with the pure old tangible solved exercise! The problem is greek universities want you only to know how to solve excersices and I don't! My subject contains operational amplifiers, transistors, current and voltage sources, photomultipliers, lock-in amplifiers, zener diodes, signal to noise measurement, ion vacuum "producers", and the like. Well, mostly the first 3 at the moment but we are getting to the others as well, and I need to be prepared. I would appreciate any solved exercises (even for math or physics) over the net I could get my "hands" on. PLEASE HELP ME!!!!!!
