It's like the art of electronics textbook. "You are new to electronics, so here is a resistor, this is a capacitor, here is an inductor, there's a thevenin equivalent, you can figure out a norton equivalent on your own, by the way lets talk about signals and band-pass filters, oh you are only on page 10?"
It should be noted that this circuit would work well only with a high impedance speaker. Typical home audio speakers have low impedance on the order of ten ohms, and would load down the high impedance output of a common emitter amplifier. To use this with a low impedance speaker, you would probably follow the common emitter stage with a common collector stage, likely in a push-pull configuration.
Wow!!! With Ce across Re, The Gain Will Be HUGE!!! With Respect To An AC Input Signal Ce Effectively Shorts Out Re leaving The Residual r'e(=.026/Ie) So Instead Of Av=-Rc/(Re+r'e) The Voltage Gain Of This Amplifier Becomes Av=-Rc/r'e which amounts to some pretty Beefy Gain!!!! r'e Typical Values Could Range from 10 to 30 ohms

Thanks for sharing...

I am not sure I am understand. Can you please teach me electronic?
Oh boy... I wonder if anybody learns anything from this teacher. I hope this isn't an intro course.
