An amplifier has an internal voltage gain (Ao) of 20, an input resistance (Rin) of 1 kΩ and an output resistance (Rout) of 75 Ω. It is connected to a voltage source (VS) of 0.5 V with a source resistance (RS) of 200 Ω and to a 1 kΩ load (RL). Using the equivalent circuit , calculate output voltage, power gain (linear and dB) of the system.
