Question
**Common-Emitter Discrete Amplifier Analysis** The following diagram represents a common-emitter discrete amplifier with specified component values: 1. **Resistors:** - \( R_{B1} = 500 \, \text{k}\Omega \) - \( R_{B2} = 100 \, \text{k}\Omega \) - \( R_C = 5 \, \text{k}\Omega \) - \( R_E = 200 \, \Omega \) - \( R_{\text{sig}} = 1 \, \text{k}\Omega \) - \( R_L = 10 \, \text{k}\Omega \) 2. **Voltage Supply:** - \( V_{CC} = 22 \, \text{V} \) 3. **Assumptions:** - Base-emitter voltage \( V_{BE} = 0.7 \, \text{V} \) - Current gain \( \beta = 90 \) - Capacitors are assumed to be short circuits for AC signals. The circuit bias analysis has yielded: - Collector current \( I_C = 2.63 \, \text{mA} \) - Input resistance \( R_{\text{in}} = 0.856 \, \text{k}\Omega \) - Output resistance \( R_{\text{out}} = R_C \) **Objective:** Given an input signal \( v_{\text{sig}} = 20 \, \text{mV}_{\text{peak}} \), determine the peak output voltage \( v_{\text{out}} \). The diagram and component values aid in understanding amplifier performance metrics such as gain, input/output impedance, and signal amplification. Calculations would typically follow for precise output voltage determination, based on amplifier design equations.

Calculations would typically follow for precise output voltage determination, based on amplifier design equations.
The image presents a multiple-choice list of peak output voltages labeled as \( V_{\text{outpeak}} \). The choices are as follows: - \( V_{\text{outpeak}} = 3.22 \, \text{V} \) - \( V_{\text{outpeak}} = 1.24 \, \text{V} \) - \( V_{\text{outpeak}} = 2.98 \, \text{V} \) - \( V_{\text{outpeak}} = 1.08 \, \text{V} \) Each option is preceded by an empty circle, indicating a selection option typical of a quiz format. This could be used in an educational setting to assess understanding of electronics and circuit theory, focusing on voltage outputs.
