A small signal source vi(t) = A cos 20t + B sin106t is applied to a transistor amplifier as shown below. The transistor has β = 150 and hie = 3 kΩ. Which expression best approximates V0(t)
v0(t) = -1500 (A cos 20t + B sin 106t)
v0(t) = -150 (A cos 20t + B sin 106t)
v0(t) = -1500 B sin 106t
V0(t) = -1500 sin 106t
