9.49 A bipolar differential amplifier having resistance Re inserted in series with each emitter (as in Fig. P9.47(a)) is biased with a constant current I. When both input terminals are grounded, the dc voltage measured across each Re is found to be 4 V T and that measured across each RC is found to be 60 V T. What differential voltage gain Ad do you expect the amplifier to have?
