INSTRUCTION

  1. The source voltage (VS) is set to 50mV at 1 KHz frequency.
  2. Keeping source voltage constant, vary the frequency from 50 Hz in regular steps.
  3. Set Source Resistance(RS)=100Ω.
  4. Set Collector Resistance(RC)=4000Ω, Set Emitter Resistance(RE)=1000Ω, Set Load Resistance(RL)=2000Ω.
  5. Set Base Resistance1(RB1)=47 KΩ, Set Base Resistance2(RB2)=10KΩ.
  6. Set Coupling Capacitor1(CC1)=10μF, Set Coupling Capacitor2(CC2) =10μF, Set Bypass Capacitance(CE)=10μF.
  7. Click on "Add to Table" button to add the readings to the table.
  8. Vary the Frequency by keeping the resistances constant.
  9. Click on "Plot" button to plot the Magnitude graph of the CE Amplifier, Frequency(Hz) along X-axis and Magnitude(dB) along Y-axis.
  10. Click on "Clear" button to take another set of readings.
