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 be

Options

A. `300cos(15t+(4pi)/(3))`
B. `300cos(15t+(pi)/(3))`
C. `75cos(15t+(2pi)/(3))`
D. `2cos(15t+(5t)/(6))`

Answer

A

Explanation

`V_(i)=2cos(15t+pi//3)`
`A_(V)=(V_(0))/(V_(I))`
`V_(0)=A_(V)xxV_(I)=300`
`V_("output")=300cos(15t+pi//3+pi)`
`V_("output")=300cos(15t+4pi//3)`
