  • There can also be DC from a previous amplifier stage passing through the volume control so it's best practice it make sure DC is not coupled to the base.

  • The Capacitor can actually provide us with isolation so if we cascade amplifier stages the dc bias from 1 amplifier stage will not effect( or in some cases place a DC load on another amplifier stage causing unstable operation of the second amplifier stage.Isolation is a key word here when it comes to the proper DC Bias conditions of a Common Emitter Amplifier

  • For To operate this amplifier half way between cutoff and saturation Vce= 1/2 Vcc, Please see my explanation of a Common Emitter Amplifier in Basic Electronics 19 under Comments!! Thanks So Much!!!

  • Awesome

    

  • WOW! Thanks so much Mr Voss. I've always wanted to know how amps work! I got 70% of what you said the first time. I think I need to watch this 2 more times to fully understand what is going on! Great Video!
