Formulate a transfer function symbolically from a set of equations from KCL and KVL

[bmulyanto]

Hi,

I would like to get the transfer function from a set of equations that I got from KCL and KVL.

I am not sure how to do it in Mathcad (Prime 5).

From here, this is what I tried.

EDIT:

sorry for the edit. I should have just gone to sleep yesterday...and mine is Prime 4.

May be so:

Hi,

sorry I was not clear.

i1 and vx should be eliminated.

EDIT: I added vx

You have three equations so you should solve for three variables.

I am not sure what exactly you are looking for - could it be something like this:

Hi,

Thanks. I got it closer.

Is there a way to make the numerator into the form like what I posted in my EDIT?

I don't think so. We have very few possibilities to influence the representation of the result of symbolic evaluations in Prime.

You may try to play around with the few keywords we have at hand, but I don't think that you will succeed

Instead of "collect, v.x" you should rather use "simplify" to let Prime cancel v.x

"factor" alone will also do this job as it applies implicit simplification.
