- What is the voltage gain?
⦿ A=18.9 (from DC analysis)
- Where is the f3db point?
⦿ f3db = 112Hz (from AC analysis)
Calculating imput impedance from f3db:
f3db = 1/(2π⋅Rin⋅C)
112=1/(2π⋅Rin⋅333⋅10⁻⁹)
Rin ≈ 4267.34Ω
- What should the output impedance be?
Check it by connecting a resistive load 7.5KΩ - using a blocking capacitor
⦿The amplitude of the output signal halves when the 7.5KΩ load is connected, so the output impedance is about 7.5KΩ
