You are given two amplifiers, A and B, to connect in cascade between a 10-mV, 100-k ohm source and a 100-ohm load. The amplifiers have voltage gain, input resistance, and output resistance as follows: for A, 100 V/V, 10 kohm, 10 kohm, respectively; for B, 1 V/V, 100 kohm, 100 ohm, respectively. Your problem is to decide how the amplifiers should be connected. To proceed, evaluate the two possible connections between source S and load L, namely, SABL and SBAL. Find the voltage gain for each both as a ratio and in decibels. Which amplifier arrangement is best?
