To determine the loaded voltage gain of the first stage, we need to consider its no-load voltage gain and the loading effect of the subsequent stage. Step 1: Identify the relevant parameters for the first amplifier stage. The first CE amplifier stage has: • No-load voltage gain, A_vNL1 = -420 • Output impedance, Z_o1 = 3.3 k Step 2: Determine the load connected to the output of the first stage. The output of the first stage is connected to the input of the second stage. Therefore, the load for the first stage is the input impedance of the second stage, Z_i2. From the diagram, Z_i2 = 1 k. Step 3: Apply the formula for loaded voltage gain. The loaded voltage gain (A_v) of an amplifier stage is given by the formula: A_v = A_vNL · (R_L')/(Z_o + R_L') where A_vNL is the no-load voltage gain, Z_o is the output impedance of the stage, and R_L' is the load connected to its output. For the first stage, substituting the values: A_v1 = A_vNL1 · Z_i2Z_o1 + Z_i2 A_v1 = -420 · Z_i2Z_o1 + Z_i2 Step 4: Compare with the given options. Comparing our derived formula with the options, option C matches: C) -420 · Z_i2Z_o1 + Z_i2 The final answer is C. That's 2 down. 3 left today — send the next one.
