    I have problem in BJT Common-Emitter Amplifier
    in green = AC
    in red = DC
    line DC the

    1) Vcut-off =Vceq + Icq *(Rc || Rl)

    or

    2) Vcut-off =Vcc - Vee

    what I use in Dc line first or second ?

    sorry for my poor English
    thanks

    For DC Vcc is a cut-off point.
