1.44 an amplifier with 40db of small-signal, open-circuit voltage gain, an input resistance of 1 m, and an output resistance of 100 , drives a load of 500 . what voltage and power gains (expressed in db) would you expect with the load connected? if the amplifier has a peak output-current limitation of 20ma, what is the rms value of the largest sine-wave input for which an undistorted output is possible? what is the corresponding output power available?
