Hello!I'm using OrCAD 16.5 lite student version for doing some BJT analysis for university.How do I remove the DC portion of the signal I view on PSPICE? It is the collector voltage of a very simplecommon emitter amplifier. I want to compare the output with the input in order to graph them and determinethe gain.
I thought of doing it by adding a trace of OUTPUT-AVG(OUTPUT) but it is not as exact as it should becauseof the first part of the signal, that little irregular transient.Any ideas on how to do it? I have seen other programs have an AC probe or AC-coupled probe..but noneof them had the Pspice signal math capabilities, or at least i did not foud them.
Thanks in advance.
PSpice does not have AC coupled probe or AC mode as found is oscilloscopes. Output- AVG(OUTPUT) would not give the desired result. if DC value is constant and known, you may want to plot the waveform by subtracting that.
Other alternative could be adding a appropriate value of capacitor in series and creating a dummy node in circuit. This node would be just for observation purpose.

Thank you alokt.Then i should do everything manually :D
Have a nice day.
