I need to find out what the voltage gain is for this CE amplifier.
I have calculated the DC voltages and currents for this circuit but I am at a loss when it come to finding the voltage gain. Can someone tell me where to start. Below is what I have for the DC part of the circuit.
VR2=15V[4.7k/(22k+4.7k)]=2.64045V
VRE=2.64045V-.7V=1.94045V
IE=1.94045V/390=4.97551mA
IC=4.97551mA
VRC=4.97551mA(1.0k)=4.97551V
VCE=15V-(1.94045V+4.97551V)=8.08404V
VC=1.94045V+8.08404V=10.02449V
VB=2.64045V
VE=1.94045V
