Question: From NCERT | NEET 2015 || [Difficult level:Hard] Subtopic: TRANSISTOR AS AN AMPLIFIER (CE-CONFIGURATION)||

.

The input signal given to a CE amplifier having a voltage gain of 150 is $V_{i} = 2 \cos [15 t + \frac{π}{3}]$ . The corresponding output signal will be:

1. $30 \cos [15 t + \frac{π}{3}]$

2. $75 \cos [15 t + \frac{2 π}{3}]$

3. $2 \cos [15 t + \frac{5 π}{3}]$

4. $300 \cos [15 t + \frac{4 π}{3}]$

.
