1. Two amplifiers are placed in a cascade. The first (leftmost) has an input resistance of 10K, an output resistance of 1K, and an open circuit gain (no load at the output) of Avo = 10V/V. The second (rightmost) has an input resistance of 20K, an output resistance of 2K, and an open circuit gain of Avo = 20V/V. Also, assume that a nonideal source with internal resistance equal to 100 Ohms is placed at the input of the cascade. The input source provides a sinusoidal input of 10V peak-to-peak. Also, assume that an 1K load is connected at the output of the cascade. What is the peak-to-peak voltage at the output of the cascade (where the load is connected)?
