Consider the following circuit where $R_S = R_B = 9 \text{ k}\Omega$, $R_E = R_L = 1.8 \text{ k}\Omega$, $\kappa\beta = 60$.
Assume an Early effect $V_A = 25V$, $V_T = 25mV$, and the transistor is operating in the active region. For the DC analysis assume $V_{BE} = 0.7V$
Find the voltage gain $V_{out}/V_S$
