How to Make a Damped Sinusoidal Source in PSPICE

So, I have been trying to verify my work recently...since I am now in the realm where solutions manuals are sparse and most problems are the product of a 30 year professor's imagination.

With that, I had a network that had a damped sinusoidal source and I wanted to verify my calculations. What to do?

Select the VSIN source from the SOURCE library
Select the source (it should turn pink)
Right click and select Edit Properties (or you could just double click the source)
There are a few parameters you should be concerned with: DF, FREQ, PHASE, and VAMPL.
If you're source looks like A*e^-Ct*cos(wt + phi) then you can update these values in the Property Editor:
DF = C (don't put a negative, PSPICE assumes that the "damping factor" is the coefficient of the "e" exponent)
VAMPL = A
FREQ = w/(2*pi)
PHASE = phi +/- 90 (if your source is a cosine)
DONE!

Now, you may have some other parameters that you need to update and that's fine. This post isn't meant to be a tell all for sources. However, the golden nugget of information is the DF parameter in the VSIN source. If you have a better or alternative way then please leave a comment.

NetBeans Error

So, I recently got the nerve up to actually "get" Java. I have done some development while working through Teach Yourself Java in 24 Hours. ...but that was all in a Linux environment. So, I tried developing using the Netbeans IDE. I was using Eclipse. I figured that I would spread the love to see what works best with me. Here's the juice: I click the little green arrow to compile my class and here is what I get-->

What did I do to fix it? I just right clicked the class and left clicked `run file'. I guess you have to point to a main class for the little green arrow to work. What up with that?

Input Resistance and Open Circuit Gain for Common Bipolar Junction Transistors

Here are some hybrid-pi models that demonstrate the small signal analysis of the common BJT configurations. These equations are universal and can be applied to any resistor/capacitor scheme. They can also be applied directly to MOSFETs. Just replace Rc=Rd, Rb=Rg, Re=Rs, and Rpi=infinity. Boom.
