You are given two amplifiers, a and b, to connect in cascade between a 10-mv, 100-k source and a 100- load. the amplifiers have voltage gain, input resistance, and output resistance as follows: for a, 100 v/v, 100k,10k, respectively; for b, 10 v/v, 10k,1k, respectively. your . 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?
