Title: Explanation how amplifier works
Post by: jimon on October 15, 2015, 10:03:55 pm

While watching some programming videos I found very nice and charismatic explanation how basic amplifier works by Gerald Jay Sussman :-+

Just check this out here : https://youtu.be/arMH5GjBwUQ?t=19m53s (at 19:53)

I especially like concept of "wiggle it" :)

An old grey beard once told me a amp is nothing more then a device that modulates it's power rail(s) based on it's input signal.
