The input signal given to a CE amplifier having a voltage gain of 150 is Vi=2cos(15t+π3) . The corresponding signal will be (in output)

Here, Input signal, Vi=2cos(15t+π3) and voltage gain, Av=150 As Av=V0Vi ∴ Out signal, V0=AvVi Since CE amplifier gives a phase difference of π(=1800) between input and output signals, ∴V0=150[2cos(15t+π3+π)]=300cos(15t+4π3)
