Click This LINK to Interact with the Simulation of Fixed Base Bias - CE Amplifier. Note that negative half cycles are nearly cut-off at the output. Also look at the presence of harmonics in the output's frequency spectrum.
Click This LINK to Interact with the Simulation of Feedback Resistor Bias - CE Amplifier.No clipping, distortion and the presence of harmonics in the output's frequency spectrum though the gain has been sacrificed a bit.
