### Understanding the Circuit Diagram This image presents an electronic circuit diagram for analysis. The circuit comprises various resistors, capacitors, and voltage sources, laid out as follows: - **Input Signal**: The left side of the diagram shows an input signal with an amplitude of \( 0.8 \text{ mV}_{\text{rms}} \) and a frequency of \( 800 \text{ Hz} \). - **Resistor (R1)**: The signal first passes through a resistor \( R1 \) with a resistance of \( 0.8 \text{k}\Omega \). - **Capacitor (C1)**: Following \( R1 \), the circuit includes a capacitor \( C1 \) with a capacitance of \( 4.7 \mu \text{F} \). - **Transistor Circuit**: - **Voltage Sources**: There are two voltage sources: 2.2V (connected in parallel with \( R2 \) and \( C2 \)) and 18V, which powers the entire circuit. - **Resistors (R2, R3, R4)**: The resistors \( R2 \), \( R3 \), and \( R4 \) have resistance values of \( 0.2 \text{M}\Omega \), \( 1.8 \text{M}\Omega \), and \( 2.2 \text{k}\Omega \), respectively. - **Capacitor (C2)**: Connected in parallel with \( R2 \), \( C2 \) has a capacitance of \( 100 \mu \text{F} \). - **Capacitor (C3)**: Added towards the output, \( C3 \) has a capacitance of \( 5 \mu \text{F} \). - **Load Resistor (\( R_O \))**: At the far right of the circuit, the load resistor \( R_0 \) has a resistance of \( 1.7 \text{k}\Omega \). - **Transistor Parameters**: - \( V_P = -2.8 \text{V} \) (Pinch-off voltage) - \( I_{\text{DSS}} = 8 \text{mA} \) (Drain-source saturation current) - \( I_{\text{DSS}} =
