    The CE amplifier has voltage gain equal to 200 and its input signal is \[0.5\,\cos \,(313\,t)\,V\]the output signal will be equal to .......... volt:-

    A)  \[100\,\cos \,(313t+90)\]

    B)  \[100\,\cos \,(313t+180)\]

    C)  \[100\,\cos \,\,(493\,t)\]

    D)  \[0.5\,\cos \,\,(313\,t+200)\]

    Correct Answer: B

    Solution :

    In CE phase diff. is \[\pi \]  and \[\frac{{{v}_{o}}}{{{v}_{i}}}={{A}_{V}}\]
