what is the Q point of the BJT(Vceq) between 0V and Vcc that maximizes the output voltage swing of a sinusoidal voltage. explain why
When the Q-point is exactly the mid-point of the DC load line, then the output voltage will have both undistorted positive half and undistorted negative half. In this case the output voltage will have a peak-to-peak value of “VCC”.
When the Q-point is below the mid-point of the DC load line, then the positive half of the output voltage is undistorted but the negative half of the output voltage is distorted.
When the Q-point is above the mid-point of the DC load line, then the negative half of the output voltage is undistorted but the positive half of the output voltage is distorted.
To get an output wave form for a sinusoidal input without any distortion in the sinusoidal wave, the Q-point must lie in the middle of the DC load line.
