1. Construct the amplifier circuit as shown in Fig. 1(a) and leave RL as an open
circuit. Be sure to use the correct polarity for the coupling capacitors (Cin and
Cout). It is likely that you already have this circuit constructed from the previous
experiment. Check that the correct bias voltages are established.
2. Apply a 0.2-Vpp 1-kHz sinusoidal signal at the input using a function generator.
Record the input and output waveforms on the oscilloscope and calculate the
voltage gain (Av).
3. To measure the output resistance (Rout) of the amplifier, add a 10-kΩ resistor
(RL) to ground at the output as shown in Fig. 4. Using the same input as in the
previous step, record the input and output waveforms on the oscilloscope and
calculate the voltage gain. The output resistance of the amplifier can be
calculated from the loading effect of RL as
