b) An input voltage source Vs of 130mV RMS and an internal resistance Rs of 100 is connected to an amplifier that has an input impedance of 3.3kN, a voltage gain of 150 and an output impedance of 2202. The output of the amplifier is connected to a speaker that has a load resistance of 2.7kn. Determine the output voltage across the speaker. Calculate the effective voltage gain. i. ii. iii. Explain how the effective gain can be increased.

Find the desired in point 54 with finding what you can find.

4) Below is the small signal model of a multistage amplifier. Using this model, write the equationsthat you would need to determine the voltagegain. IMPORTANT: You only need to providethe equations that you would need to determinethe voltage gain. You DO NOT need to combine and simplify the equationsto determine a final expression for the voltagegain. Vin Vo Vb vo1 Rb R13 Vbe1 Vbe2 'e gm 1 Vbe1 gm 2 Vbe2 Rc2 Rc1 Re
