    Hi,
    I have some problem in following circuit please help me.

    Determine Voltage Gain (Av) of Common Emitter amplifier circuit with and without bypass capacitor.
    values:
    1. RC = 3.3k ohm
    2. RE = 680 ohm
    3. r'e = 30 ohm

    I know Rc is Collector Resistance and RE for Emitter Resistance, but what is r'e?

    And please tell me following formulas are correct?
    Av = Rc/Re (calc with bypass capacitor)
    Av=Rc/r'e+Re (calc without bypass capacitor)
    Thanks
