. For the circuit shown in Fig. 2, draw a complete small-signal equivalent circuit utilizing an appropriate
T model for the BJT (use a=0.99). Your circuit should show the values of all components, including the
model parameters. What is the input resistance Rin? Calculate the overall voltage gain (Vo/Vsig)
