Hi All,
This may end up being a very simple question for some of you advanced folks. I have been using Mathcad for years, but not always at a great depth, and somewhat sporadically.
Anyhow, I was working through some circuits in the s-domain, and MathCad works really well here to quickly narrow down the equations...certainly faster than by hand.
I have attached the file with my question at the very bottom of of the calculations.
I would really like to solve this circuit for Vo/Vi to arrive at the s-domain transfer function. Is there a one-step solver in Mathcad for this? I know how to use the symbolic solver to find a solution for any single variable, but wondering if there is a way to find the expression for Vo/Vi?
Please don't laugh too hard if I'm missing something obvious through my ignorance. I have hunted through Mathcad's help and some of the other community entries out here and have not found anything like this.
Thanks!
Solved! Go to Solution.
Doh! Never mind...I see that I have an extra term in the numerator that is screwing me up. This circuit has offset and I missed this term before writing my question. My mistake.
Anyhow, faults aside with my initial question, is there a way to directly solve for an expression like Vo/Vi if I didn't have this extra term?
Thanks
Maybe that way:
Very slick! Thank you for the help!
Werner, this solution has given me a powerful tool in my MathCad arsenal, and is exactly the help I needed in properly using MathCad for this solution. Thanks for taking the time to share!
-MF-, Very sorry I have not been available to post a circuit...my priorities were shifted to a different project and I have not been able to get back to this. As I said, I found a couple of errors in my original equation, but with my most recent solution, it seems to track the actual circuit. If I get the chance, I will still come back and post to satisfy your (and my) curiosity.
Hi,
something does not convince me. Could you add a copy of the circuit?
Thank you.
Yes, of course. I found an error in my initial calculations, but will fix it and re-send with a pic of the circuit. I am away from the office today, but will attempt to put something together for you here. Thank you.
