Engineering Simple RC Circuit Voltage Division Solution

AI Thread Summary
The discussion revolves around solving a voltage division problem in the s-domain for a simple RC circuit. The initial attempt yields a transfer function H(s) of 1/(s+1), leading to an inverse Laplace transform resulting in Vin*e^(-t). However, there is confusion regarding the expected output voltage, Vout, which should be Vin(1-e^(-t)). Participants suggest that the original problem may be incomplete and emphasize the importance of correctly transforming the input signal. Clarifying these points is essential for accurately determining the voltage across the capacitor.

Homework Statement



I think I am turning retarded. For some reason I can't get the right values for a simple voltage division in the s-domain. Find Vout in terms of Vin

Homework Equations


The Attempt at a Solution



So I do H(s) = (1/s) / ((1/s) + 1 ) = 1/(s+1)
Then Inverse Laplace transform it and get Vin*e^(-t). But shouldn't Vout=Vin(1-e^(-t)) ?

So I think I am ending up with the voltage drop across the resistor instead of the capacitor like it should be...

Can you post the whole problem? I'm quite sure you have left something important out. One error I can see right now is, you haven't laplace transformed the pulse signal.
 
Thanks so much! That's what I was forgetting.
