a) Determine the voltage gain of the amplifier, Vout / Vin, in terms of the parameters in the given circuit.

b) Determine the overall voltage gain between the source and the output, Vout / Vsourse, in terms of the parameters in the given circuit.

Attempt at Solution:

I attempted condensing the resistors.

(Ro * Rl) / (Ro + Rl) becomes the new resistor on the right side.

[ (Rb * Rin) / (Rb + Rin) ] + Rs becomes the new resistor on the left side.

After this I am lost. Can anyone help me out here?
