Read the Amplifier class notes.
For the amplifier circuit shown, RS = 1 kΩ, and RL = 27 Ω.
For amp 1: Ri1 = 3.3 kΩ, A1= 15, Ro1 = 150 Ω.
For amp 2: Ri2 = 120 Ω, A2= 10, Ro2 = 330 Ω.
For amp 3: Ri3 = 390 Ω, A3= 5, Ro3 = 33 Ω.
If the amplitude of the input signal is vi = 0.8 V, find the amplitude of the amplified output singnal, vo.
