The input signal given to a CE amplifier having a voltage gain of 150 is Vi=2 cos (15t+π/3). The corresponding output signal will be
Options
(a) 75 cos(15t+2π/3)
(b) 2 cos(15t+5π/6)
(c) 300 cos(15t+4π/3)
(d) 300 cos(15t+π/3)
Correct Answer:
300 cos(15t+4π/3)
Explanation:
Voltage gain Av= 150
Vi = 2 cos (15t+π/3); V₀=?
For CE transistor phase difference between input and output signal is π=180⁰.
Using formula, Av=V₀/Vi
⇒V₀=Av x Vi
=150 x 2 cos (15t+π/3)
V₀=300 cos (15t + π/3 + π)
V₀=300 cos (15t + (4/3) π)
