Hey there!
I did learned many basic and intricate workings of Multivibrators inside the IC555 timer in my college - they are okay and quite understandable because of the R-S flip-flop thingy (I build a truth table for this) and the pair of comparators.
Unfortunately, the discrete versions AIN'T easy. The last part - Astable using 2 BJTs are horribly difficult to be understood. I know there's positive feedback inside these configurations, like the ones in Op-amps, but the discrete versions just made my head spin.
To be honest, I can build up all three types of multivibrators using IC555 myself with the aid of my knowledge, but NOT any of these discrete versions.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Anyone has experience learning the discrete versions of these Multivibrators in college?![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
