Question

do not answer it , if you do not know how to use pspice

Vc 15Vdc R2 Rc 5k 150 C2 01 C1 RL 02N2222 Vin 50k R1 Re VAMP L-50mV FREQ 5000Hz Ce 10uF 1k 50 Figure 1: A Common-Emitter Amplifier Circuit Configuration 4. Refer to Fig. 1 in the handout; simulate the circuit in PSpice and obtain the input-output waveforms (to calculate the voltage gain) for a sinusoidal input with a magnitude of 10 mV and the frequencies of 2000Hz, 5000Hz and 10000Hz (one-at-a-time). Also, increase the input voltage magnitude to 3 V and observe the circuit output. Justify the results.

here first 3 cases with input 10mV and next 3 cases with input 3V in the second case you can observe the harmonic distortion in positive side.
