Emitter-Bias circuit including ree and bypass capacitor

00:42:15

Ie=Ic; Ie can be found from multifunction meter
Vbe=0.7

Vbb>IeRe + Vbe
Re=(from 0.1 to 0.5)Rc 
Vc=Vcc/2
Rc=Vc/Ic

ree=26mV/Ie; e.g. if Ie=0.001V than ree=0.026/0.001=26 ohm

Rb=hfe((Vbb-Vbe)/Ie - ree - Re)

C=1/(2*pi*f*Xc); where f - lowest frequency, Xc reactance; Xc=0.1*Re or less
