Assume the transistor has the characteristics VBE=0.7V,VA=,=150 and that IB (base current) was calculated to be 6.85A. 3) The voltage gain vo/vi is approximately (need to use re along with the emitter resistanc i) -28.07 ii) -78.02 iii) -20.87 iv) -27.08 4) If vs=0.3cos(3000t)V, the output voltage vo is approximately i) 6.23cos(3000t)V ii) 23.33cos(3000t)V iii) 8.39cos(3000t)V iv) 8.10cos(3000t)V
