The input signal is given to a CE amplifier having a voltage gain of 150 is V i = 2 cos ⁡ 15 t + π 3 . The corresponding output signal will be:

Options

  1. A75 cos ⁡ 15 t + 2 π 3
  2. B2 cos ⁡ 15 t + 5 π 6
  3. C300 cos ⁡ 15 t + 4 π 3
  4. D300 cos ⁡ 15 t + π 3

Correct answer

C. 300 cos ⁡ 15 t + 4 π 3

Step-by-step solution

CE amplifier causes phase difference of π = 180 o s o V o u t = 300 cos ⁡ 15 t + π 3 + π
