Input signal of a CE amplifier, V_{i} = 2\cos \left ( 15\:t+\frac{\pi }{3} \right )

Voltage gain = 150

As CE amplifier give phase difference of \pi between input and output signals,

so A_{v} = \frac{V_{0}}{V_{i}} \Rightarrow V_{0} = A_{v}\cdot V_{i}

V_{0} = 150 \times 2\cos \left ( 15\:t+\frac{\pi }{3} + \pi \right )

V_{0} = 300\cos \left ( 15\:t+\frac{4\pi }{3} \right )
