Hey guys,

I've had an assignment which asks me to design a circuit in PSPICE, fabricate the real thing and test it.

In the assignment instructions it says this:

· Complete PSPICE simulation, including the following (30 %):
1. DC analysis
2. Frequency response (using .ac)
3. Large signal analysis (using .tran) including distortion analysis.

DC analysis I have under control. The same with frequency response.

Large signal analysis. What is this? And how to I simulate this in PSPICE?

PS: If you're interested: here is my schematic.

I'm not sure if this is right, but I did a "transient response" using the default settings and the following graph was produced:

Is the transient a single impulse? Is it a step? What is it?

 

Sorry to double post.. But I think I may have it.

I used VPULSE as a source this time. With:
TD = 0
TR = 5ns
V1 = 0
V2 = 1V
everything else blank.

And the output plot is:

But is that "Large Signal" and is that what they're after do you think?
