Answer 1

Q] ____?

300 cos [ 15t + 4π / 3 ] !

Explanation:

Input signal of a CE amplifer

Vin = 2cos [ 15t + π /3 ]

Voltage gain Av = 150

As CE amplifier gives phase difference of π

Between input and output signals.

So, Av = Vo / Vin

=> Vo = Av Vin

Vo = 150 × 2cos [ 15t + π /3 + π ]

V = 300 cos [ 15t + 4π /3 ]
