The input signal given to a `CE` amplifier having a voltage gain of `150` is `V_(i)=2cos(15t+(pi)/3)`. The corresponding output signal will beA. 100 sin `(10 t + pi/3)`B. `100 sin (10 t + (4pi)/3)`C. `200 sin (10 t + (2pi)/3)`D. `100 sin (10t + pi)`

Answer» Correct Answer - B
For output signal `V_o` = 50 x 2 and phase is `(10 t + pi/3 + pi)`
`therefore ` Output signal is 100 sin `(10t + (4pi)/3)`
