4. In the following circuit, assume R2 = 80 kΩ and the amplitude of the input voltage is 100 mV. Calculate the amplitude of the output voltage in mV. Hint: The Amplitude of the output voltage is the input amplitude times the voltage gain.

VCC = 12V
VEE = -12V
R1 = 10 KΩ

Without knowing the specific configuration of the circuit, we cannot determine the voltage gain and therefore cannot calculate the amplitude of the output voltage. More information is needed.
