4) Run the simulation. Configure the timebase and scales for channels A and B, as shown in Figure 5.

Record the readings into Table 1. 6) For all amplifiers, voltage gain (Av) is defined as the following. Vout Ay Vin Calculate Ay based on the readings from Step 5 and enter the value into Table 1. Important: Keep both Vin and Vout either all mV or V. And, Av has no unit because the units will cancel out. =

7) Adjust the RED and BLUE vertical bars, calculate the phase difference beween Vin and Vout (in degree), and fill the value into Table 1. Table 1 Vin (mv) Vout (V) Av Phase Difference Between Vin and Vout 8) Transfer the table to ECT226 Project Deliverables Module 5. 9) Copy and paste two screenshots to ECT226 Project Deliverables Module 5. ● The BJT amplifier circuit schematic from your Multisim design ● The simulation results displayed on the oscilloscope XSC1 along with proper settings
